Generating charge carriers with lifetimes long enough to drive catalysis is a critical aspect for photoelectrochemical and photocatalytic systems, key determinant of their efficiency. Metal oxides are widely explored as photoanodes water oxidation. However, application limited by the disparity between picosecond–nanosecond electrons holes photoexcited in bulk metal versus millisecond–second tim...

Nanoporous metals with bicontinuous ligament-channel structure are of great importance in catalysis, electro-catalysis, actuation and energy storage conversion. However, the intrinsic brittleness nanoporous has always been “Achilles heel” that impedes their practical applications. Utilizing vapor pressure difference metals, herein we propose a flexible general phase alloying (VPA)-dealloying st...

From a personal view, this perspective analyses the gaps and opportunities for catalysis to address electrification of chemical production from high-tech scenario. It is assumed that significant substitution fossil fuels required meet net-zero emissions targets. This vision significantly impacts future sustainable production. We identified short (up 2030), medium- (2030–2040) long-term (2040–20...

The synthesis and applications of composites based on layered double hydroxides (LDHs) nanocarbons have recently seen great development. On the one hand, LDHs are versatile 2D compounds that present a plethora applications, from medicine to energy conversion, environmental remediation, heterogeneous catalysis. other, unique physical chemical properties owing their low-dimensional structure sp2 ...

group viii b metal oxides supported on gamma-alumina were investigated as catalysts and promoters of moo3 hydrodesulfurization catalysis. superior promotion was observed in pbo promoted catalyst compared to that of coo, the typically accepted promoter. other metal oxides, sno and ho2o3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for coo promoted catalyst.
