In this paper, the reported MOF ([Co(bimip)(HO)]·0.5HO) was employed in photocatalytic CO reduction, antibacterial, and dye adsorption experiments. The photocatalytic activity of the MOF for CO reduction was systematically investigated. The high average CO generation rate of 3421.59 μmol·g·h after 12 h confirms the efficient photocatalytic CO reduction ability of the MOF. At the same time, the MOF can completely inhibit the growth of and within 24 h when its concentration reaches 400 μg/mL and 500 μg/mL, respectively. The MOF has an adsorption capacity for CR. The adsorption rate was 83.42% at 60 min, and the adsorption capacity of the MOF for CR reached 500.00 mg·g.

Semiconductor nanowires have become emerging photocatalysts in artificial photosynthesis processes for solar fuel production. For reduction reactions, semiconductor photocatalysts with high reducing powers are highly desirable, especially for chemicals that are extremely difficult to reduce. This study introduces a new semiconductor photocatalyst, scandium (Sc)-III-nitrides, which have higher reducing powers than all conventional semiconductor photocatalysts.

Photocatalytic transformation of nitrate (NO) in wastewater into ammonia (NH) is a challenge in the detoxification and recycling of limited nitrogen resources. In particular, previously reported photocatalysts cannot promote the reaction using water as an electron donor. Herein, we report that copper-doped titanium dioxide (Cu-TiO) powders, prepared via the sol-gel method and subsequent calcination, promote NO-to-NH reduction in water.

The photocatalytic reduction of CO in water to produce fuels and chemicals is promising while challenging. However, many photocatalysts for accomplishing such challenging task usually suffer from unspecific catalytic active sites and the inefficient charge carrier's separation. Here, a site-specific single-atom Ni/TiO catalyst is reported by in situ topological transformation of Ni-Ti-EG bimetallic metal-organic frameworks.

In this work, bimetallic organic frameworks NH-MOFs(Fe, Ti) with different Fe/Ti molar ratios were prepared by a hydrothermal method for the synchronous redox transformation of Cr(VI) and As(III). These results showed that NH-MIL-125(Ti) was less effective in the photocatalytic removal of Cr(VI), whereas NH-MIL-88B(Fe) was less effective in the photocatalytic oxidative removal of As(III). Due to the introduction of Fe, the photocatalytic reduction removal of Cr(VI) (23.

In the face of escalating environmental challenges such as fossil fuel dependence and water pollution, innovative solutions are essential for sustainable development. In this regard, zeolitic imidazolate frameworks (ZIFs), specifically ZIF-8, act as promising photocatalysts for environmental remediation and renewable energy applications. ZIF-8, a subclass of metal-organic frameworks (MOFs), is renowned for its large specific surface area, high porosity, rapid electron transfer ability, abundant functionalities, ease of designing, controllable properties, and remarkable chemical and thermal stability.
