“…The XPS results demonstrate chemical reduction of metallic Ru with 26.0% atomic percentage on the surface of Co 3 B-CoP, which are much lower than that of Co 3 B (56.5%), indicating that the surface characteristics of the composite can effectively adjust the chemical state of attachments. Similar examples of reduced metallic Ru content and increased RuO 2 content were also observed for P-vacancy-rich CoP surfaces in our previous study [45]. This preprint research paper has not been peer reviewed.…”

“…In addition, the catalytic performance of the magnetic M/CoFe 2 O 4 nanocatalyst was also compared with recent literature in the catalytic hydrolytic dehydrogenation of NaBH 4 . − Figure shows that the catalytic activities of as-obtained magnetic Ru/CoFeO 4 and Pd/CoFe 2 O 4 nanocatalysts are fairly acceptable, with TOFs of 93.5 and 74.8 L H 2 ·g cat –1 ·min –1 (421 and 348 mol H 2 ·mol cat –1 ·min –1 ), respectively.…”

Sodium borohydride (NaBH 4 ) has been widely regarded as the one of most promising further hydrogen (H 2 )generated materials for the safe storage, transportation, and utilization of H 2 . Therefore, the exploration of more efficient catalytic systems for on-demand H 2 evolution via NaBH 4 hydrolysis is critical. Herein, a series of magnetic recyclable cobalt ferrite (CoFe 2 O 4 )-modified transition-metal nanoparticles (including Ru, Pd, Rh, Pt, Ir, and Ag) for the catalytic hydrolytic dehydrogenation of NaBH 4 for H 2 evolution have been developed for the first time. The order of the catalytic activity is Ru > Pd > Rh > Pt > Ir > Ag, indicating that Ru/ CoFe 2 O 4 and Pd/CoFe 2 O 4 are the most active, with turnover frequencies of 421 and 348 mol H 2 •mol cat −1 •min −1 . By comparing with other carriers, we found the key factor to be CoFe 2 O 4 in facilitating H 2 production upon the hydrolytic dehydrogenation of NaBH 4 in this work.

“…[26] Additionally, the Ru 3d 5/2 spectra display two prominent peaks at 280.5 and 281.9 eV, assigning to metallic Ru 0 and oxidized Ru 4 + . [27] The Ru content (45.6 %) in Ru/Co 3 BÀ Co(OH) 2 @NF was approximately twice higher that of bÀ Ru/Co 3 BÀ Co(OH) 2 @NF (27.4 %). Of note, due to the strong interaction between Ru precursors and the substrate, the calcination provides more porosity without aggregating Ru clusters.…”

Developing a highly efficient bifunctional catalyst for hydrolysis of metal hydrides and spontaneous hydrogen evolution reaction (HER) is essential for substituting conventional fuels for H2 production. Herein, Ru‐cluster‐modified Co3B−Co(OH)2 supported on nickel foam (Ru/Co3B−Co(OH)2@NF) is constructed by electroless deposition, calcination and chemical reduction. The catalyst exhibits an excellent hydrogen generation rate (HGR) of 4989 mL min−1 normalgcatalyst-1 ${{{\rm g}}_{catalyst}^{-1}}$ and good reusability, superior to most previously reported catalysts. Besides, Ru/Co3B−Co(OH)2@NF displays a prominent hydrogen evolution reaction catalytic capability with a low overpotential of 153.0 mV at 100 mA cm−2 (50.5 mV at 10 mA cm−2), a small Tafel slope of 40.0 mV dec−1 and long‐term stability (100 h@10 mA cm−2) in 1.0 M KOH. The excellent catalytic H2 generation capacity benefits from the rapid charge transfer promoted by metallic Co3B, the synergistic catalytic effect of Co3B−Co(OH)2 and Ru clusters, and the unique composite structure favorable for solute transport and gas emission.
