Summary: In this study, Ni-Co bimetallic nanoparticles were successfully synthesized, and the effects of different Ni contents on particle size and polydispersity were observed. Ni50Co50 showed the highest catalytic activity for the hydrolysis of alkaline NaBH4 solutions. The kinetic studies revealed that the hydrolysis rate increased with higher NaBH4 concentration and decreased with higher pH value of the solution. The activation energy of the reaction decreased with decreasing NaBH4 and catalyst contents.

Summary: A highly efficient catalyst composed of carbon nanospheres supporting ultrafine bimetallic Pt-Co nanoparticles was successfully synthesized for hydrogen evolution from NaBH4 hydrolysis in this study. The catalyst exhibited outstanding performance in kinetic and thermodynamic tests, with high hydrogen generation rate and low activation energy. The hydrolytic mechanism was investigated using isotopic tracer method and mass spectrometric analysis, showing that the catalyst maintained high catalytic activity even after five cycles of performance tests.

Summary: This study prepared hydrochars from pine cones and rheum ribes shells through the hydrothermal method and used them as catalysts in the hydrolysis of sodium borohydride. The synthesized catalyst hydrochars were characterized by various techniques. The results showed that the hydrochars from pine cones and rheum ribes shells had both amorphous and crystalline structures. The BET surface areas of the two hydrochars were determined to be 1.6 m2/g and 19.01 m2/g, respectively. The hydrolysis kinetics of sodium borohydride in the presence of these hydrochars were investigated.

Summary: The catalytic activities of Au NPs and Au-CuO catalysts were studied in OSRM and CO oxidation reactions. It was found that the addition of an optimal amount of NaBH4 resulted in small-sized and uniformly distributed Au NPs catalysts, which exhibited higher catalytic activity in the OSRM. The Au-CuO catalysts showed the highest methanol conversion rate, while the monometallic Au catalyst had almost five times higher catalytic CO oxidation activity.

Summary: A SiO2@PAA catalyst composed of silica nanoparticles modified with poly(acrylic acid) was developed for NaBH4 methanolysis, showing excellent catalytic performance. The catalyst exhibited significantly higher hydrogen generation rate and lower activation energy compared to unmodified silica. Furthermore, the catalytic activity of the SiO2@PAA catalyst could be restored after regeneration with diluted hydrochloric acid solution.

Summary: In the study, it was found that cobalt catalysts are more active than nickel catalysts in the hydrolysis of sodium borohydride. One reason for the lower activity of nickel catalysts is the presence of hydrogen on its surface, which interferes with reactant adsorption. The addition of cobalt to nickel catalysts can enhance hydrogen generation rate.

Summary: A novel RuW/MWCNT catalyst was synthesized successfully for the hydrolysis reaction of NaBH4. The addition of W to Ru on MWCNT support increased the catalyst activity. Surface characterization of the catalyst was performed using SEM-EDX, XRD, XPS, and TEM analysis methods. The hydrolysis performance of RuW/MWCNT catalyst was investigated by studying parameters including temperature, catalyst amount, NaBH4 concentration, and NaOH concentration.

Summary: Co-Fe-B@g-C3N4/Cu sheet was successfully prepared via chemical deposition process. The optimized weight of g-C3N4, 0.005 g, resulted in a catalyst with unique surface structure that exhibited improved catalytic performance in the hydrolysis of NaBH4 solution. Under visible light irradiation, a HGR of 8343 mL•min-1•g-1 and Ea of 48.4 kJ•mol-1 were achieved, surpassing most reported non-precious metal and precious metal catalysts. This work offers a viable method for manufacturing non-noble metal catalysts with high catalytic properties in the hydrolysis of NaBH4 solution.
