This review focuses on polyhedron-engineered Pt-based nanocrystals as highly active ORR catalysts for PEMFCs.
Highly reductive RGO (reduced graphene oxide)/ZnIn2S4 nanocomposites with a sheet-on-sheet morphology have been prepared via facile one-pot solvothermal method in mixture of N,N-dimethylformamide (DMF) and ethylene glycol (EG) as solvent.

Exploiting efficient photocatalysts with strengthened structure for solar-driven alcohol oxidation is of great significance. The photocatalytic performance graphitic carbon nitrides can be considerably promoted by modulating its crystallinity. Results confirmed that a high crystallinity accelerates the separation and transfer photogenerated charge carriers, thus providing more free charges photoredox reactions. More importantly, facilitated adsorption benzyl desorption benzaldehyde...
