TLDR
A bioinspired iron-based catalyst with semiconductor photocatalytic functions in combination with a high surface area holds promise for synthetic chemistry via combining photocatalysis with organosynthesis through using g-C(3)N(4) nanoparticles.Abstract:
A bioinspired iron-based catalyst with semiconductor photocatalytic functions in combination with a high surface area holds promise for synthetic chemistry via combining photocatalysis with organosynthesis. Here exemplified for phenol synthesis, Fe-g-C3N4/SBA-15 is able to oxidize benzene to phenol with H2O2 even without the aid of strong acids or alkaline promoters. By taking advantage of both catalysis and photocatalyisis functions of g-C3N4 nanoparticles, the yield of the phenol can be markedly promoted.read more

Confined Catalysis in the g-C3N4/Pt(111) Interface: Feasible Molecule Intercalation, Tunable Molecule-Metal Interaction and Enhanced Reaction Activity of CO Oxidation
TL;DR: This work uses first-principles calculations to systematically explore a novel nanospace constructed by placing a 2D graphitic carbon nitride (g-C3N4) nanosheet over a Pt(111) surface, and finds that the energy barrier depends mainly on the properties of the molecule and the channel.
