Serious challenges in energy and the environment require us to find solutions that use sustainable processes. There are many sustainable electrocatalytic processes that might provide the answers to the above-mentioned challenges, such as the oxygen reduction reaction (ORR), water splitting, the carbon dioxide reduction reaction (CO₂RR), and the nitrogen reduction reaction (NRR). These reactions can enhance the value added by producing hydrogen energy through water splitting or convert useless CO₂ and N₂ into fuels and NH₃. These electrocatalytic reactions can be driven by high-performance catalysts. Therefore, the exploration of novel electrocatalysts is one of the important electrocatalytic fields. In this paper, we aim to systematically discuss a variety of electrocatalysts used for sustainable processes and to give further insights into their status and associated challenges. We invited many famous research groups to write this roadmap with topics including platinum (Pt) and its alloys for ORR, oxides for ORR, chalcogenides for ORR, carbon-based hollow electrocatalysts for ORR, carbides for ORR, atomically dispersed Fe–N–C catalysts for ORR, metal-free catalysts for ORR, single-atom catalysts (SACs) for ORR, metal boride (MB) electrocatalysts for water splitting, transitional metal carbides (TMCs) for water splitting, transition metal (TM) phosphides for water splitting, oxides for water splitting, sulfides for water splitting, layered double hydroxides for water splitting, carbon-based electrocatalysts for water splitting, Ru-based electrocatalysts for water splitting, metal oxides for CO₂RR, metal sulfides for CO₂RR, metals for CO₂RR, carbon for CO₂RR, SACs for CO₂RR, heterogeneous molecular catalysts for CO₂RR, oxides for NRR, chalcogenides for NRR, C₃N₄ for NRR, SACs for NRR, etc. Their contributions enabled us to compile this 2020 roadmap on electrocatalysts for green catalytic processes and provide some suggestions for future researchers.

能源和环境方面的严峻挑战要求我们找到使用可持续流程的解决方案。有许多可持续的电催化过程可能为上述挑战提供答案，例如氧还原反应 (ORR)、水分解、二氧化碳还原反应 (CO ₂ RR) 和氮还原反应 (NRR) . 这些反应可以通过分解水产生氢能来提高附加值，或将无用的 CO ₂和 N ₂转化为燃料和 NH ₃. 这些电催化反应可以由高性能催化剂驱动。因此，探索新型电催化剂是重要的电催化领域之一。在本文中，我们旨在系统地讨论用于可持续过程的各种电催化剂，并进一步了解它们的状态和相关挑战。我们邀请了许多著名的研究小组来编写这个路线图，主题包括用于 ORR 的铂 (Pt) 及其合金、用于 ORR 的氧化物、用于 ORR 的硫属化物、用于 ORR 的碳基空心电催化剂、用于 ORR 的碳化物、原子分散的 Fe-N-C ORR 催化剂、ORR 无金属催化剂、ORR 单原子催化剂 (SAC)、水分解金属硼化物 (MB) 电催化剂、水分解过渡金属碳化物 (TMC)，₂ RR，对于CO金属硫化物₂ RR，金属为CO ₂ RR，碳为CO ₂ RR，诸SAC为CO ₂ RR，对于CO异构分子催化剂₂ RR，氧化物为NRR，硫属化物为NRR，C ₃ Ñ ₄为NRR 、用于 NRR 的 SAC 等。他们的贡献使我们能够编制 2020 年绿色催化过程电催化剂路线图，并为未来的研究人员提供一些建议。
