A twin absorption system was installed by Kobe Group (Kobe Univ. and Technova Inc.) for simultaneous D2 and H2 gas absorption experiments using Pd micronized particles and oxide composites of nano-sized Pd and Zr [2]. The samples tested so far include the 0.1-μm-diam. Pd powder (Nilaco Corporation) [2], 300- mesh Pd-black powder (Nilaco Corp.) [2], a Pd×Zr oxide composite “PZ” (Santoku Corporation) [3-9], a Ni×Zr oxide composite “NZ” (Santoku Corp.) [4], a Pd×Ni×Zr oxide composite “PNZ” (Santoku Corp.) [4], and another Pd×Ni×Zr oxide composite “PNZ2B” [8,9] provided by Brian Ahern, Vibronic Energy Technologies Corporation. The phenomenon is thought to be very sensitive to mesoscopic structure of the sample as well as the degree of oxidization [6-9]. To clarify the mechanism of anomalous heat evolution, study of material characterization is discussed in the present paper. The characterization methods include SEM, XRD, Laser Raman microscopy, TEM and PIXE analyses. Preliminary measurements have indicated some structural changes after absorption experiments.

Mt-02 Effect of Forced Oxidization on Hydrogen Isotope Absorption/Adsorption Characteristics of Pd×Ni×Zr Oxide Compounds Y. Miyoshi1, H. Sakoh1, A. Taniike1, A. Kitamura1, A. Takahashi2, R. Seto2 and Y. Fujita2 1Graduate School of Maritime Sciences, Kobe University, Kobe 6580022, Japan 2Technova Inc, Tokyo 1000011, Japan In order to confirm heat and He4 generation by deuterium (D) absorption in nano-sized Pd powders reported by Arata and Zhang [1], we established a twin absorption system for simultaneous D2 and H2 gas absorption experiments using Pd micronized particles and oxide composites of nano-sized Pd and Zr [2]. In the present work, three kinds of samples are tested; the Pd×Zr oxide composite “PZ” and a Pd×Ni×Zr oxide composite “PNZ”, both supplied by Santoku Corporation, and another Pd×Ni×Zr oxide composite “PNZ2B” provided by Brian Ahern, Vibronic Energy Technologies Corp. Simultaneous introduction of the D2 and H2 gases into each reaction chamber from each reservoir tank is performed with flow rate control by “Super Needle” valves. The as-received samples are oxidized to some extent. To investigate the effect of oxidization on sorption (absorption and/or adsorption) rate and heat release rate, we applied forced de-oxidization and forced oxidization (to make 5 – 10 % PdO or NiO) to the samples. Oxidization was made at 473 K or 573 K in oxygen gas at a pressure of 0.3 MPa(a), while deoxidization was made at 573 K in D2 (H2) gas at a pressure of 0.3 - 0.5 MPa(a). The D2 (H2) absorption runs have revealed the following facts for the 1st phase [2, 3], where predominant heat evolution associated with hydrogen isotope sorption proceeds; 1. Forced de-oxidization of the PZ and PNZ samples gave greatly reduced loading ratio D(H)/M and heat release rate compared to very large values for as-received samples, which were recovered significantly by forced oxidization. 2. Time-resolved measurements have been applied to the PZ samples to reveal existence of sub-phases, 1a and 1b. In the 1a-phase, the anomalously large heat evolution proceeds under relatively low pressure below 3 kPa, while relatively small amount of heat is generated in the 1b-phase under relatively high pressure (3 – 10 kPa) with significant isotope dependence. Oxygen incorporation is necessary for the 1a-phase to appear. 3. Time-resolved specific sorption energy, or differential heat of hydrogen uptake, hD(t) (hH(t)), defined as the output energy per one hydrogen isotope atom absorbed/adsorbed is very large; hD (hH) » 1.33 eV/D (1.15 eV/H) for the 1aphase, and hD (hH) » 0.47 eV/D (hH » 0.41 eV/H) for the 1b-phase, respectively as averaged values in their intervals. 4. For the PNZ2B sample, the effect of de-oxidization on the rates is very modest, and forced oxidization made almost perfect recovery. We observed anomalous change of gas pressure in the early stage of sorption caused probably by the effect of surface NiO layer, and anomalously large D(H)/M ratios exceeding 3.0. The averaged value of the differential heat of hydrogen uptake, [D (hH) » 0.61 (0.55) eV/D(H), has a modest isotopic effect of about 10%. However, similarly to the case of PZ samples, [D sometimes exceeded hH several times in some time intervals, which might be of nuclear origin. References: [1] Y. Arata and Y.

Taniike1, R. Seto2 and Y. Fujita2 1Kobe University & 2Technova Inc. Japan The Kobe group continues to study underlying physics in the observed anomalies in D(H)-gas loading experiments with nanometal( M)-particles/metal-oxide samples[1-3], since 2008. The observed anomalies are summarized as: 1. Very rapid MD(H)x over-full loading (x>1) under near “zero pressure” of D(H)-gas is reproducibly attained for Pd/ZrO2 (PZ) and Pd/Ni/ZrO2 (PNZ) samples. 2. Anomalously large released heat (0.6-2.0 eV/D(H)) in Phase-I period for PZ and PNZ samples, compared with known value about 0.2 eV/D(H) for bulk Pd metal (PP) sample, is reproducibly observed. Energy gain (sorptionenergy/ desorption-energy) for D is near 10. 3. By the forced oxidization (several % PdO formation) of used PZ and PNZ samples, surprising recovery of performances on loading ratio (x>1) and heat release level (0.9- 1.5eV/D(H)) has been repeatedly observed, while by the de-oxidization the performances got back to the near bulk ones (0.25-0.28 eV/D(H), x=0.4-0.7) for PZ sample. 4. To study dynamics of D(H)-sorption (adsorption /absorption), time-dependent measurements of evolutions for D(H)/M ratios and [-values (energy per a D(H)-sorption) have provided interesting data with very large isotopic effects, which suggests some “nuclear effects”. We discuss mechanisms to answer why such “chemical + nuclear” anomalies take place in “mesoscopic” particles confined in metaloxides. A special role of PdO surface layer is modeled to scope the generation of surface sub-nano-holes (SNH). SNH may trap D(H)- clusters on surface with deep adsorption potential, providing seeds of 4D/TSC-induced 4d fusion (23.8MeV/4He-product). It enhances D(H)-diffusion into Pd lattice sites of nano-particle, and at the end of Phase-I realizes the x>1 state with “very deep (1.5- 1.8 eV for PZ)” global trapping potential (GPT) of “mesoscopic catalyst”. In GPT there holds local shrunken Bloch potentials for MD(H) lattice to induce the non-linear D(H)-oscillation mode that enhances very much the TSC (tetrahedral symmetric condensate) formation probability in the nano-particle.
