Heterogeneous catalysts are of paramount importance to the world economy and the sustainable development of our society, from chemical manufacturing to energy-related applications and environmental remediation. The overall apparent activity of a catalyst in a reaction can be expressed as a mathematical product of the active site density (SD) and turnover frequency (TOF).

1. Introduction. Ever-increasing energy demands and growing global environmental concerns associated with excessive fossil fuels usage are stimulating a broad, intensive search for renewable energy techniques to resolve serious energy crisis this field, lithium-ion batteries (LIBs), supercapacitors (SC),,, and electrocatalytic water-splitting, have recently emerged as three kinds of ...

Hydrogenating TiN, by milling in pure H 2, led to depletion of reactive nitride, and ammonia production halted within 1.5 h. Milling titanium in a mixed feed (N 2 and H 2) resulted in continuously increasing ammonia yields with increasing milling time. Milling for 12 h resulted in four times more ammonia than hydrogenating TiN.

In order to compare the electrocatalytic activity, a volcano curve as a function of average Gibbs free energy of atomic hydrogen adsorption was plotted. The SiPF-Bpy-CTF, a predicted model structure, occupy a position close to the top of the volcano. From this work, it was discovered that ΔG H* is related to the band gap. Such a low band gap ...
