Many universities and prominent institutes make experiments with metal powder and hydrogen. The Max Planck Institute for example examines the heat storge capacity at 400° for such arrangements. They also mill powder in ball mills in hydrogen athmossphere to research the hydrogen storage capacity. Many others do similar experiments and research. They try all tricks possible to optimize the effects. Anomalous energy is not reported. They have probly tried any arrangements one could think about. So I think, all chemicals can been excluded as a catalyst.
I remember experiments that I made in my youth: rebuilding Marconis wireless telegraph. As a receiver I used a glass tube filled with iron powder. 2 electrodes where in the iron powder, a battery, a lamp and the antenna and ground where connected to it. In german the name of this device is "Kohärer". When this arrangement receives RF frequency, the iron particles melt together, the arrangement becomes conductive and the lamp lits up. When the glass tube is shuttered, the melting points are broken and the current is interrupted. This can be repeated ad infinitum. They used this in early history of wireles telegraphy in combination with an electromagnetic hammer, and automated the process. Without doubt, if the current is high enough, high temperatures will develop at the microscopical contact points. If the current is too high the process is not reversible. Rossi mentioned high temperatures (1500°C) inside his device. It is clear, that at the melting points there is high temperature. It is clear this would not work with nanopowder. The particles would glue together irreversible. There must be a optimal particle size that is above the nanometer scale. Could this be the catalyst? High frequency and low DC current applied to the powder at the same time in a hydrogen athmosphere? Peter
