Roles of MXenes in Photocatalysis

Abstract

Artificial photocatalysis is beneficial to carbon neutrality, renewable resources generation and sustainable society development. Due to the unique layered structure, abundant surface functional groups and tunable electronic properties, Maxine is emerging as a promising contender to improve the comprehensive performance for photocatalysts. Much progress has been made in the study of MXene‐based nanomaterials over the past years, and state‐of‐the‐art advances in the rational design, controllable synthesis, characterization techniques and diverse applications of MXene‐based photocatalysts have been reviewed. However, the roles and perspectives of MXenes in photocatalysis have been less summarized. Based on the analysis of physical/chemical properties of MXenes and the latest research progress, herein we discuss the multiple roles of MXenes in promoting photocatalysis, including carrier for active site anchoring, light‐transmitting media, mass transfer medium, cocatalyst and heat conductor. In addition, current status and challenges of MXenes in photocatalysis are summarized, and the future directions as well as the bottleneck of development need to be broken through for MXenes in photocatalysis are also proposed. This review provides a clear and in‐depth understanding of the physical/chemical properties of MXene‐based photocatalysts and their contributions for photocatalysis.This article is protected by copyright.

Synergistic Enhancement of Carrier Migration by SnO2/ZnO@GO Heterojunction for Rapid Degradation of RhB

“…With the rapid development of society in recent years, environmental concerns have grown more prominent, and environmental degradation has become a key challenge confronting humans. The indiscriminate release of industrial, agricultural, and home wastewater has resulted in water contamination, and is therefore of significant concern [ 1 , 2 ]. Water pollution can cause damage to ecosystems as well as jeopardize human health.…”
