Axil-- You do not mean to coat the surface of the Ni nano particles themselves do you? It seems only the inner surface of the reactor vessel which is a small pressure vessel, rather than the nano particles should be coated. However, it may be desirable to transmit the infrared across the reactor vessel wall to the external coolant to effect better heat transfer.
One other suggestion is in order to achieve the size control of the Ni nano particles, developers should consider ball milling Ni in a cryogenic ball milling machine using N ( maybe liquid H) as the liquid in the process. The N (and potentially H) will coat every small particle with a thin--one or two atom layer-- of N (or H) during the process and assures that particles do not agglomerate during the milling process. Better size uniformity will likely be accomplished in the process. Cost effectiveness for production of nano Ni in house may be significant. The Ni particle surface resulting may be more active for LENR. The loading of the reactor vessel could be accomplished as a slurry of liquid N or H as the case may be with a warming period to evaporate the N or H. For a H slurry loading of the reactor could be accomplished in the same warming operation as the H turns to a gas. (Liquid N would be safer and cheaper to use than liquid H in the milling operation.) Lastly the homogeneous distribution of any catalyst could effectively be accomplished during the milling operation, which effectively mixes all constituents in the machine. The coating of each particle as it is attrited in the operation is significant in achieving a homogeneous mixture, if this is desirable. Development would be necessary to make sure the ball milling operation, as it is perfected, produces nano size particles of the correct dimensions and mixed catalysts as desired. Whatever milling balls are selected they should be very hard compared to the Ni or catalyst being attrited. For example Haynes-25 cobalt alloy balls may be warranted.

Furthermore, the ideal thin film thickness of nickel to optimize optical performance is between 10nm and 13 nm. All surface on your Ni/H reactor should be coated with a nickel thin film whose thinness is between 10nm and 13 nm.
