By constructing an atomically coherent covalent heterojunction ZnIn₂S₄/ZnCo₂O₄, efficient charge separation was achieved through an ultra-low lattice mismatch of 1.64%. Combined with the photothermal effect of ZnCo₂O₄, near-infrared light response was extended, resulting in excellent performance in photocatalytic hydrogen evolution and selective oxidation of benzyl alcohol. This provides a new paradigm for full-spectrum photocatalytic synergistic conversion. (J. Mater. Sci. Technol., 2026, 251, 135-148).

An S-scheme Mn_0.5Cd_0.5S/In₂S₃ heterojunction photocatalyst was designed. Efficient degradation of tetracycline hydrochloride was achieved through optimized interfacial charge transfer. The influence of reaction parameters was elucidated by response surface methodology. Toxicity assessment of degradation products confirmed environmental safety, providing an effective solution for the treatment of emerging pollutants in water bodies. (Chin. J. Catal., 2025, 75, 147-163)

An inverted F-type ZnWO₄/In₂S₃ heterojunction was innovatively designed. By modulating the interfacial electric field, it overcame the charge recombination limitation of traditional Type-I heterojunctions, achieving efficient tetracycline degradation (76% removal rate) and complete detoxification. The developed continuous-flow reaction system demonstrated promising application potential. (Carbon Energy, 2026, DOI:10.1002/cey2.70179).

A donor π-skeleton engineering strategy was proposed to prepare highly crystalline conjugated microporous polymer Py-TDO. Efficient charge transport channels were constructed through intermolecular π-π stacking, enabling a CO₂-to-CO conversion rate of 223.97 μmol g^-1 h^-1 without sacrificial agents. This provides a new pathway for developing metal-free photocatalytic CO₂ reduction materials. (Carbon Energy, 2025, 7, e70025).

A lattice-matched ZnIn₂S₄/ZnCo₂S₄ heterojunction (lattice mismatch only 0.05%) was developed. Synchronous electron-proton transport was achieved via built-in electric field and hydrogen spillover effect, resulting in a hydrogen evolution rate of 70.3 mmol g^-1 h^-1 and a benzaldehyde selective oxidation efficiency of 39.3 mmol g^-1 h^-1 (selectivity 93.6%). This addresses the key bottleneck of asynchronous charge separation and proton transport in photocatalytic reactions. (Sci. China Mater., 2026, DOI:10.1007/s40843-025-3889-6).

A lattice-matched NiCo₂S₄@Zn_0.5Cd_0.5S heterojunction was constructed. Ohmic contact was utilized to enhance charge transfer. Combined with the photothermal properties and catalytic activity of NiCo₂S₄, a hydrogen evolution rate of 92.9 mmol g^-1 h^-1 and a benzaldehyde selectivity of 96% were achieved. This provides an important reference for the design of synergistic photothermal-photocatalytic conversion systems. (J. Mater. Sci. Technol., 2026, DOI:10.1016/j.jmst.2026.01.003)
