Structural modification of defective WO by g-CN for photocatalytic gold recovery from non-cyanide-based plating effluent.

A set of nCN/WO composites was synthesized through a simple thermal treatment for gold recovery from the simulated effluent of a non-cyanide-based plating bath. The obtained results exhibited that all nCN/WO composites demonstrated a higher photocatalytic activity for gold recovery than their pristine components due to the formation of nanocomposites which paved a convenient pathway for charge transfer. Among all synthesized composites, the 5.

Plasmonic-enhanced catalytic activity of methanol oxidation on Au-graphene-Cu nanosandwiches.

The plasmonic-enhanced catalytic activity of methanol oxidation on Au-based catalysts provides a promising strategy for direct methanol fuel cells (DMFCs) to avoid the CO poisoning of traditional Pt-based catalysts. However, the effect of surface plasmon resonance on the light-enhanced methanol oxidation activity of Au or Au-based catalysts has not been fully understood. The mechanism by which hot plasmonic carriers participate in the methanol oxidation reaction (MOR) has not been elucidated.
