Due to the insufficient light absorption capacity and low efficiency of photogenerated electron-hole separation, their catalytic activities still need to be further improved. Plasma cocatalyst is considered as a promising strategy to expand light absorption range and facilitate separation efficiency of photogenerated charges for inorganic semiconductor photocatalysts, thereby also beginning to be explored and applied in the MOFs-based photocatalysts. However, due to the usual lattice mismatch or large growth differences between metals and MOFs, interface barriers exist, which to some extent hinders the effective transmission of photogenerated electrons. Build-in electric field (IEF) of the interface could be used as the driving force to overcome the interface barriers, promoting the transfer of charge carriers. Herein, the non-noble metal Bi and ordinary MIL-125 are chosen as plasma cocatalyst and MOF object, respectively, forming Bi/MIL-125 composite via an <em>in-situ</em> reduction strategy. The experimental results and theoretical calculation demonstrate that an IEF is formed and pointed from Bi to MIL-125. And metal Bi possesses obvious plasma light absorption and carrier capture capabilities. Built-in electric field in coordination with Bi plasma co-catalytic effect realizes the highly efficient photocatalytic CO₂ reduction. The optimized BM-110 demonstrates a 10.4-fold higher CO production rate relative to the initial MIL-125, recording a yield of 96.63 µmol g⁻¹ h⁻¹.

In spite of the lack of solubility of PET, the depolymerization pathway is shifted from a solid-liquid interfacial process to a pseudo-houmogeneous reaction through judicious cosolvent selection. Furthermore, <em>π-π</em> interactions between the cosolvent and PET modulate the electron density and nucleophilic character of the ester bonds, facilitating their activation by Lewis acid catalysts. Complementarily, microwave irradiation enables rapid and uniform heating via the synergistic dielectric response of ethylene glycol (high dielectric loss tangent) and a bifunctional ZnO catalyst (serving as both microwave absorber and substrate catalyst). The synergistic cosolvent-microwave system lowers the apparent activation energy for PET glycolysis from 185 to 45 kJ·mol^–1, attaining 100% PET conversion and 97.5% bis(2-hydroxyethyl) terephthalate (BHET) yield at 150 °C within 20 min.
