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 (HO) 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.
最近，共催化策略在解决芬顿体系的瓶颈方面取得了重大进展。一系列使用各种无机金属共催化剂和有机共催化剂的共催化策略已经在各种氧化剂（即过氧化氢（HO）和过硫酸盐）体系中得到了发展，显著提高了催化性能，降低了氧化剂消耗（仅为传统芬顿/类芬顿体系的 5-10%）。然而，这些共催化策略从理论理解到实际应用和未来指导策略的发展都被忽视了，这是共催化系统未来规模化应用必须考虑的一个重要问题。在本文中，通过比较共催化机制以及它们的优缺点，对具有低氧化剂消耗特性的共催化策略进行了综述。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规模化性能。此外，还首次通过技术经济分析（TEA）、生命周期评估（LCA）和机器学习（ML）的结合，概述了具有低氧化剂消耗特性的共催化策略的未来发展指导策略。最后，本文从理论理解到实际应用和未来指导策略，系统地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，这项工作从理论理解到实际应用和未来指导策略，对具有低氧化剂消耗特性的共催化策略进行了系统的综述。
