Summary: In this study, a highly efficient photocatalytic system for H-2 production is developed using porphyrins as photocatalysts. Self-organization of PdTCP and PtTCP into H- and J-aggregates on TiO2 NPs is crucial for H-2 evolution, with J-aggregated PtTCPs showing higher efficiency than H-aggregated PdTCPs. The simultaneous adsorption of PdTCP and PtTCP onto TiO2 NPs results in the most efficient catalytic system, achieving high turnover numbers.

Summary: Solar fuel production methods like water splitting and CO2 reduction through sunlight-assisted catalytic reactions are attractive and sustainable, but single photocatalytic materials often fall short in meeting all the requirements. Hybridization with metal organic frameworks (MOFs) can address these limitations and lead to the design of high-performance photocatalysts, offering diverse possibilities for energy generation. MOF-derived hybrids inherit the advantages of MOFs and provide further options for enhancing solar fuel production.

Summary: Despite efforts to develop efficient Ti-based metal-organic framework (MOF) photocatalysts, MIL-125-NH2 remains the benchmark, and few design principles have been offered to improve photocatalytic performance. Linker functionalization in Ti MOFs has been shown to enhance photocatalysis under visible light by closing the electronic band gap and improving charge carrier lifetimes. The role of node nuclearity and topology on photocatalytic activity in known Ti-based MOFs is still unclear. Here, we report a new MOF, ICGM-1, with a 3D-connected framework featuring 1D Ti-O rods. Photocatalytic hydrogen evolution experiments reveal a significant difference in activity, solely attributed to node geometry. Time-resolved spectroscopy and DFT calculations explain these differences in terms of electronic and geometric properties, paving the way for the development of Ti-MOF photocatalysts.

Summary: Catalyst-facilitated amine regeneration provides an energy-efficient and economically feasible CO2 capture process. Glucose-derived carbon sphere nanocatalysts with isethionic acid functionalization were developed to optimize the CO2 desorption rate of CO2-loaded monoethanolamine solutions. The synthesized catalysts accelerated the CO2 desorption rate by up to 108% and reduced the heat duty by approximately 10.8% compared to traditional uncatalyzed regeneration. These catalysts can be separated easily, stable in cyclic uses, and suitable for industrial-scale applications. Regenerating solvents with catalysts at 86°C allows the use of low-grade industrial waste heat, enabling efficient CO2 capture facilities to be installed at various industrial sites for achieving net zero emissions by 2050.
