Summary: In this work, a method for capturing and converting CO2 into liquid fuel (HCOOH) and fertilizer (NH4H2PO4) under ambient conditions is reported. The method involves the capture of CO2 by a (NH4)2CO3 aqueous solution, which is then hydrogenated into HCOONH4 using a PdAu nano-alloy catalyst. The results show that the method achieves a CO2 capture capacity of 0.56 mmol/g and a conversion rate of 32.6% under ambient conditions. Further characterizations reveal that the PdAu alloy and the nearby amine group on the catalyst enhance the adsorption of HCO3-, thus boosting the catalyst activity. This study offers a simple and useful strategy for the conversion of CO2 into high-value-added chemicals.

Summary: This study utilizes an engineered enzymatic catalyst in a batch reactor to convert CO2 into formic acid (as formate). By adjusting the operating voltage, implementing an O2 scavenger, and controlling system pH, both formate production and Coulombic efficiency can be maximized. The peak formate production and efficiency achieved in long-term experiments were 225 mM and 91%, respectively, showing the potential for effective CO2 conversion to formate.

Summary: The smart catalyst shows temperature-controlled catalytic activity in releasing hydrogen from ammonia borane, with high catalytic activity at room temperature and significantly suppressed hydrogen generation at high temperature. The switchable red luminescence of the composite hydrogel in solution at high/low temperatures offers the possibility to track the catalyst and understand the catalytic mechanism. This thermo-controllable system of hydrogen generation has great potential applications in the safe hydrolysis from chemical hydride fuel.

Summary: The study demonstrates that the DN-FSP process is more efficient in engineering NM0-TiO2 nanophotocatalysts due to better surface dispersion and narrower size distribution of the noble metal. Additionally, DN-FSP promotes the formation of intraband states in NM0-TiO2, reducing the band gap of the nanophotocatalysts.

Summary: The development of low-carbon technologies for efficient use of hydrogen as an energy carrier is crucial. The cost of hydrogen production is expected to become a key factor along with efficiency, safety, and transport. Formic acid has been identified as an efficient energy carrier for hydrogen storage, and transition-metal molecular catalysts for formic acid dehydrogenation have shown promise. This review outlines recent advances in these catalysts, evaluates their cost for industrial implementation, and identifies challenges and limitations in scaling up the technology.
