Programming Bifunctional Metal–Organic Frameworks to Integrate Multiple Triboelectric Nanogenerators for Green Electronics toward Effective Self-Powered Photocatalytic System

Programming and synthesizing bifunctional materials for regulating the output of triboelectric nanogenerators (TENGs) and their photocatalytic efficiency is a promising strategy for energy harvesting to build self-powered systems. Herein, we tackle this challenge by introducing metal-organic frameworks (MOFs) as molecular catalysts and triboelectric layers for self-powered photocatalytic systems. A zeolite-like mixed-valence MOF (
