Minimalist Second-Sphere Engineering with Polyvinyl Alcohol Drives Cooperative Hydrolysis in Zn(II) System

Key Points

The study aims to explore how partially hydrolyzed polyvinyl alcohol can induce enzyme-like effects in zinc systems.
Utilized partially hydrolyzed polyvinyl alcohol (PVA80) as a disordered material.
Conducted hydrolysis experiments in the presence of zinc ions.
Analyzed the cooperative effects generated by the PVA80 material.
Demonstrated increased hydrolysis rates in the zinc system with the addition of PVA80.
Showed that second-sphere effects significantly enhance catalytic activity compared to control systems.

Abstract

First sphere engineering has enabled potent artificial phosphatases, but strategies that generate enzyme-like second-sphere effects with simple disordered materials remain limited. Here we demonstrate that partially hydrolyzed polyvinyl alcohol (PVA80,...
