Multi-stepwise electron transfer via MOF-based nanocomposites for photocatalytic ammonia synthesis

Abstract

Photocatalytic ammonia (NH3) synthesis can realize the reaction of nitrogen (N2) and water by using solar energy as the sole driving force under mild conditions, however, the inferior electron transfer...

Dual Heterojunction of Etched MIL‐68(In)‐NH2 Supported Heptazine‐/Triazine‐Based Carbon Nitride for Improved Visible‐Light Nitrogen Reduction

“…[11] Recently, polydopamine and carbon nitride nanosheets were decorated on UiO-66 with a gradient energy band for enhanced electron transfer efficiency in photocatalytic nitrogen fixation. [12] MIL-125-NH 2 @MIL-125-OH core-shell nanoparticles were loaded by TiO 2 to establish a dual heterojunction and the ternary nanocomposites exhibited better photocatalytic hydrogen production activity than the singleheterojunction counterparts. [13] Heptazine-/triazine-based carbon nitride (HTCN) isotype heterojunction composed of heptazine-based carbon nitride (HCN) and triazine-based carbon nitride (TCN) has shown superior photocatalytic activity than HCN and TCN because the structural phase engineering can provide efficient paths for the transport and separation of photogenerated electron-hole pairs due to the built-in electric field.…”
