Quantum Sphere has been making this kind of NiO nanopowder for many years. It is available now but not cheap.

Several others here may have found no excess heat. Brad Lowe sent his supply to Ryan Hunt and that group was apparently planning a run with it. The QSI first application was actually water splitting – and it does lower the voltage required - but it does not split water well enough to compete with the alternative process (water-gas shift) From: Patrick Ellul A cheap hydrogen generator that relies on a nickel nanoparticle may be the game-changer we have been waiting for. https://beta.cosmosmagazine.com/physical-sciences/hydrogen-fuel-water-almost-within-our-grasp
