“…Proper modification of the cathode can strengthen the 2e-ORR and weaken the 4e-ORR and other side reactions. For example, Le et al enhanced the hydrophilicity and electrochemical performance of the carbon felt cathode through hightemperature heat treatment as Figure 6d exhibited, realized greater current response and improved electron transfer efficiency, resulting in a significant expansion of the electro- [82] 20 mg/L mixed dyes NPS-x 0.05 M Na 2 SO 4 ; pH 2; 0.2 mM Fe 2 + --98 % in 150 min Chen et al [83] 1650 mg/L RR X-3B CNT/NCB-GDE 0.2 M Na 2 SO 4 ; pH 3; 0.2 mM Fe 2 + 400 Air, 1.5 L/min 100 % in 60 min Lu et al [84] 20 mg/L diclofenac 310T/CB@NF 0.05 M Na 2 SO 4 ; acidic pH --92 % in 2 h Zou et al [85] 10 mg/L tetrabromobisphenol A MOFs/CF 0.05 M Na 2 SO 4 ; pH 3 --98 % in 60 min Wang et al [86] Chemistry-A European Journal active surface area of the obtained porous carbon cathode.

Catalytic hydrogen peroxide (H2O2) generation from oxygen and water enables a sustainable environment to operate in an effective and green energy‐to‐chemical conversion way, which has attracted increasing interest in the fields of energy production and environment treatment. In light of this, tremendous progresses and developments have been made during the past decades in catalytic H2O2 production for pollutant removal from three perspectives including photocatalysis, electrocatalysis or chemical activation. Herein, we critically review the state‐of‐the‐art developments over various procedures of H2O2 generation and its further application, with the existence of photocatalysts, electrocatalysts, and catalysts, respectively. Benefiting from extensively experimental and theoretical investigations, the performance and stability of H2O2 generation and its utilization can be maneuvered by devising catalytic platform based on numerous catalysts with predominant electronic, chemical and physical properties, which endow the catalysts with efficient electrons transportation, abundant active sites, and sufficient oxygen adsorption for H2O2 generation. Furthermore, this review also discusses the formation mechanism of H2O2 by 2e‐ORR and 2e‐WOR, as well as its functional process of activating and removing pollutants, and summarizes the design principles of various catalysts by focusing on the formation of H2O2. We finally highlight the specific challenges and prospects related to the utilization of catalysts and envision the possible future development trends in the fields of pollutant removal.

Fenton processes allow to degrade and mineralize toxic organic contaminants, yet classical Fenton processes require continuously adding hydrogen peroxide and ferrous ions, costly solution pH adjustment, and treatment of secondary iron sludge pollution. Heterogeneous electro-Fenton processes deliver oxidizing radicals with only oxygen and electricity consumed. Bifunctional catalysts allow the synthesis and activation of hydrogen peroxide simultaneously, eliminate additional chemical reagents, and yield no metal residues in treated water. Here, we review bifunctional catalysts for heterogeneous electro-Fenton processes. We describe the mechanisms of oxidizing radical generation from oxygen. Then, we compare different types of bifunctional catalysts based on their elemental compositions: (1) metal/carbon composite catalysts, i.e., monometallic iron/carbon composite catalysts, bimetallic/trimetallic carbon composite catalysts, and transition metal single-atom catalysts; (2) metal composite catalysts without carbon; and (3) metal-free carbon catalysts. Then, we present five other approaches beyond electrocatalysts, which have been used to improve the performance of heterogeneous electro-Fenton processes.
