“…Even so, we summarize the best performance for various reactions catalyzed by different heteroatoms‐doped carbons in Figure for easy comparison. [ 118–158 ] As can be seen, N‐doped carbon catalysts show better catalytic performance over other heteroatom‐doped carbons for ORR and water splitting. For non‐N‐doping, only B‐doping has been reported for ORR, P‐doping for OER, and F‐doping for HER to show catalytic performance comparable to the N‐doping.…”

Ten years have passed since the discovery of the first nitrogen‐doped carbon‐based metal‐free catalyst for the oxygen reduction reaction, which opened a new field of catalysis toward a large variety of important applications, ranging from energy conversion and storage to environmental remediation. Various heteroatom‐doped carbons, beyond nitrogen‐doping (N‐doping), with distinctive features have also been developed for many specific reactions of practical significance (e.g., oxygen reduction (ORR), water splitting (OER and HER), CO2 reduction (CO2RR), and N2 reduction (NRR)). However, the topic of metal‐free non‐N‐doped carbon electrocatalysts has not been reviewed till now. This article aims to review recent advances in non‐N‐doped carbon electrocatalysts with an emphasis on their synthesis, catalytic mechanisms, and catalytic performance in various electrochemical reactions, including the ORR, OER, HER, H2O2 production, NRR, and CO2RR. Like N‐doping, boron‐doping, phosphorus‐doping, and fluorine‐doping are found to show similar catalytic efficiency for the ORR, OER, and HER. However, oxygen‐doping and boron‐doping are particularly favorable for the selective production of H2O2 and NH3, respectively, exceeding the performance of N‐doping. Along with the timely and critical overview on the non‐N‐doped carbon electrocatalysts, current challenges and future perspectives for this emerging field are also discussed.

“…The porous Ni 3 FeN used as both anode and cathode in two-electrode system for overall water splitting in 1.0 M KOH required a voltage of 1.495 V at 10 mA cm −2 , which could be driven by a battery with rated voltage of 1.5 V [ 50 ]. Metal-free electrocatalysts also show high activity, good stability and low cost to replace metal-based electrocatalysts for long-term water splitting [ 54 , 55 ]. Yu, Chen, Dai et al reported a novel metal-free bifunctional electrocatalyst with the ultrathin exfoliated black phosphorus (EBP) nanosheets on N-doped graphene (EBP@NG).…”

HIGHLIGHTS • Bifunctional electrode and electrolytic cell configuration for electrochemical water splitting are reviewed. • The different green energy systems powered water splitting are summarized and discussed. • An outlook of future research prospects for the development of green energy system powered water splitting in practical application process is proposed. ABSTRACT Hydrogen (H 2) production is a latent feasibility of renewable clean energy. The industrial H 2 production is obtained from reforming of natural gas, which consumes a large amount of nonrenewable energy and simultaneously produces greenhouse gas carbon dioxide. Electrochemical water splitting is a promising approach for the H 2 production, which is sustainable and pollution-free. Therefore, developing efficient and economic technologies for electrochemical water splitting has been an important goal for researchers around the world. The utilization of green energy systems to reduce overall energy consumption is more important for H 2 production. Harvesting and converting energy from the environment by different green energy systems for water splitting can efficiently decrease the external power consumption. A variety of green energy systems for efficient producing H 2 , such as two-electrode electrolysis of water, water splitting driven by photoelectrode devices, solar cells, thermoelectric devices, triboelectric nanogenerator, pyroelectric device or electrochemical water-gas shift device, have been developed recently. In this review, some notable progress made in the different green energy cells for water splitting is discussed in detail. We hoped this review can guide people to pay more attention to the development of green energy system to generate pollution-free H 2 energy, which will realize the whole process of H 2 production with low cost, pollution-free and energy sustainability conversion.
