We report a novel TiO₂ nanocrystals photocatalyst confined by ZIF-67-templated porous CoS_x, with conductive Ti₃C₂ boosting the transport efficiency of the charge carriers.

Nanoporous Co-doped Zn_1−xCd_xS fabricated with ZnCo-ZIFs as templates afford a high H₂-production rate, corresponding to 45.2 and 422.2 times larger than those of Zn_0.5Cd_0.5S and CdS without using ZIF as template.

A novel drug delivery system, containing functional Fe₃O₄, CdTe@ZnS QDs, doxorubicin and a chitosan matrix, was designed via a polymer crosslinking method.

A visible light-driven cadmium-free ZnS/rGO/CuS porous photocatalyst heterojunction was synthesized by simple hydrothermal and cation exchange methods using a zeolitic imidazolate framework (ZIF-8) as the template and Zn precursor. Due to the ZIF-8 templated high porous microstructure and/or the high carrier conductivity of the graphene (rGO), ZnS/CuS and ZnS/rGO/CuS heterojunctions exhibited a photocatalytic H₂-production activity 9 and 13 times larger than that of the counterpoint heterojunction derived from the inorganic precursors under visible light irradiation, respectively. This work will provide an insight into the design and synthesis of ternary composite photocatalyts with high porosity and efficient charge separation and transfer.
