Core-Shell Covalently Linked Graphitic Carbon Nitride-Melamine-Resorcinol-Formaldehyde Microsphere Polymers for Efficient Photocatalytic CO Reduction to Methanol.

Photocatalytic reduction of CO with light and HO to form CHOH is a promising route to mitigate carbon emissions and climate changes. Although semiconducting metal oxides are potential photocatalysts for this reaction, low photon efficiency and leaching of environmentally unfriendly toxic metals limit their applicability. Here, we report metal-free, core-shell photocatalysts consisting of graphitic carbon nitride (g-CN, CN) covalently linked to melamine-resorcinol-formaldehyde (MRF) microsphere polymers for this reaction.

Ultrathin 2D TiC MXene Co-catalyst anchored on porous g-CN for enhanced photocatalytic CO reduction under visible-light irradiation.

Constructing an efficient photocatalyst is critical for photocatalytic carbon dioxide (CO) into valuable fuel. Herein, a high-efficiency catalyst was synthesized by a simple one-step electrostatic self-assembly method, in which TiC (TC) was anchored on porous g-CN (PCN) with rich -NH via NH-Ti bond. Such a chemical interaction made the optimized TC/PCN-2 with 2 wt% loading of TiC possess highest CH production (0.

In situ fabrication of amorphous TiO/NH-MIL-125(Ti) for enhanced photocatalytic CO into CH with HO under visible-light irradiation.

A series of amorphous TiO/NH-MIL-125(Ti) (Am-TiO/NM) composites were in-situ fabricated via one-pot facile water (HO) bath method. The photocatalytic performance of as-synthesized samples was evaluated by CO reduction with HO under visible-light irradiation. The Am-TiO/NM with 22.
