Catalytic reduction of organic analytes has aroused substantial attention due to the significant role they have been playing in both fundamental and industrial fields. However, there still lacks a new catalytic mechanism since similar catalytic reduction pathways are frequently reported based on the literature review (e.g., the catalytic reactions generally controlled by the pseudo-first-order kinetics). In this contribution, the catalytic pathway is flexibly varied by tuning the microstructure of a ternary composite catalyst consisting of silver ions, graphene, and polyacrylamide. The pseudo-zero-order kinetics is, for the first time, realized using such metal ions-based catalysts. The in-depth structural characterizations and analyses of the catalysis pathway and performance are provided.
