Metal-Organic Frameworks-Derived Nanocarbon Materials and Nanometal Oxides for Photocatalytic Applications.

Harnessing low-density solar energy and converting it into high-density chemical energy through photocatalysis has emerged as a promising avenue for the production of chemicals and remediation of environmental pollution, which contributes to alleviating the overreliance on fossil fuels. In recent years, metal-organic frameworks (MOFs) have gained widespread application in the field of photocatalysis due to their photostability, tunable structures, and responsiveness in the visible light range. However, most MOFs exhibit relatively low response to light, limiting their practical applications.

Synergistic Enhancement of Photocatalytic H Evolution over NH-MIL-125 Modified with Dual Cocatalyst.

The construction of efficient photocatalysts for water splitting to enable H evolution is pivotal to alleviate energy issues and environmental concerns. In this work, carbon dots (CDs) were prepared by employing "green solvent" ionic liquids as carbon sources and then combined with Pt/NH-MIL-125, resulting in the emergence of a high-efficiency photocatalyst termed CDs-Pt/NH-MIL-125 for the first time. This composite photocatalyst exhibited outstanding photocatalytic activity in H production under visible light irradiation.
