Recent Advances and Future Perspectives of Transition Metal‐Supported Carbon with Different Dimensions for Highly Efficient Electrochemical Hydrogen Peroxide Preparation

Abstract Electrocatalytic oxygen reduction to hydrogen peroxide (H 2 O 2 ) is one of the most promising methods to replace the conventional anthraquinone route for the green and facile synthesis of H 2 O 2 . Owing to the outstanding electrochemical active surface area and fast charge transfer capability of carbon nanomaterials or nanostructures with different dimensions, such as 1D, 2D, and 3D, various strategies including nanostructure engineering, defect engineering, and interface engineering have been proposed to promote the catalytic activity of carbon‐based catalysts toward two‐electron (2e − ) oxygen reduction reaction (ORR) for H 2 O 2 generation over the past decade. In this review, the latest progress, major achievements, and prospects of the transition metal‐supported carbon with different dimensions for highly efficient electrochemical H 2 O 2 preparation via the 2e − ORR process are summarized. The rational design principles and synthetic strategies of transition metal‐supported carbon are systematically introduced while the representative advances, the identification of active sites, and their possible catalytic mechanisms toward the H 2 O 2 production are discussed. Finally, according to the current development stage and existing shortcomings of 2e – ORR catalysts for H 2 O 2 production, the challenges and prospects of transition metal‐supported carbon with different dimensions are also summarized.
