Recently, great effects have been made for the co-catalysis strategy to solve the bottlenecks of Fenton system. A series of co-catalysis strategies using various inorganic metal co-catalysts and organic co-catalysts have been developed in various oxidant (i.e., hydrogen peroxide (H2O2) and persulfate) systems with significantly promotion of catalytic performances and lower oxidant consumption (only 5–10 % of conventional Fenton/Fenton-like systems). However, the developments of these co-catalysis strategies from theoretical understandings to practical applications and future guiding strategies were overlooked, which was an essential problem that must be considered for the future scale-up applications of co-catalysis systems. In this paper, these co-catalysis strategies with low-oxidant-consumption characteristics have been reviewed by the comparison of their co-catalysis mechanisms, as well as their advantages and disadvantages. We also discussed the recent developments of amplifying devices based on the co-catalysis systems. The scale-up performances of co-catalysis strategies based on these amplifying devices have also been assessed. In addition, future guiding strategies for the development of co-catalysis strategy with low-oxidant-consumption characteristics have also been first time outlined by the combination of the technical-economic analysis (TEA), life cycle assessment (LCA) and machine learning (ML). Finally, the paper systematically discusses the development opportunities, technical bottlenecks and future development directions of co-catalysis strategies with the prospect of large-scale applications. Basically, this work provides a systematic review on co-catalysis strategy with low-oxidant-consumption characteristic from theoretical understandings to practical applications and future guiding strategies.

低氧化剂消耗类芬顿化学的共催化策略：从理论理解到实际应用及未来指导策略


近年来，共催化策略在解决Fenton体系的瓶颈方面取得了很大的效果。在各种氧化剂（即过氧化氢（H2O2）和过硫酸盐）体系中开发了一系列使用各种无机金属助催化剂和有机助催化剂的助催化策略，显着提高了催化性能并降低了氧化剂消耗（仅5 – 传统芬顿/类芬顿系统的 10%）。然而，这些共催化策略从理论认识到实际应用的发展以及未来的指导策略却被忽视了，这是共催化系统未来放大应用必须考虑的一个重要问题。本文对这些具有低氧化剂消耗特性的助催化策略进行了综述，比较了它们的助催化机理及其优缺点。我们还讨论了基于共催化系统的放大装置的最新发展。还评估了基于这些放大装置的共催化策略的放大性能。此外，还首次结合技术经济分析（TEA）、生命周期评估（LCA）和机器学习，勾勒出未来低氧化剂消耗特性共催化策略发展的指导策略。毫升）。最后，论文系统讨论了具有大规模应用前景的共催化策略的发展机遇、技术瓶颈和未来发展方向。 基本上，本工作从理论理解到实际应用以及未来的指导策略对具有低氧化剂消耗特征的共催化策略进行了系统的综述。
