Efficient hydrolytic dehydrogenation of ammonia borane over ultrafine Ru nanoparticles supported on biomass-derived porous carbon

Waste-biomass-derived activated carbon supported Co–Cu–P nanocatalysts for hydrolytic dehydrogenation of ammonia borane

“…1(a) demonstrates the AC morphology, and the carbonized surface is representative and in good accord with literature results. 10,14,15 High-resolution TEM image in Fig. 1(b) clearly shows the porous nature.…”

“…To evaluate the structural defects and the degree of graphitization, the intensity ratio of the D-and Gbands (I D /I G ) was calculated to be 1.26, indicating carbon in the obtained AC is mainly present in the form of disordered carbon. 10,11,15,18,19 Fig. 1(e) exhibits the N 2 adsorption/desorption isotherms, and specic surface area of the AC was calculated to be 1590 m 2 g −1 according to the well-known BET equation, which is comparable to some commercial AC material such as YP-50.…”

“…1(c), two weak and broad diffraction peaks around 29°and 42°correspond to the (002) and (100) planes of the graphite carbon, respectively, implying low ordering. [10][11][12][13][14][15] Fig. 1(d) shows the Raman spectrum of the obtained AC, and the typical D-and G-bands located at 1340 and 1590 cm −1 can be assigned to the disordered carbon crystallites and crystalline graphite, respectively.…”

“…As reported in recent literature, there are many kinds of biomass used for AC production, including cattail, cotton, walnut shell, shaddock endothelium, pinecone shell, corn straw, and so on. [10][11][12][13][14][15] In our present work, waste ginkgo leaves were collected for the preparation of AC via traditional hydrothermal carbonization and alkali-assisted activation. In situ phosphidation method was conducted for the synthesis of Co-Cu-P nanocatalysts immobilized on the waste-biomass-derived AC, and the Co/Cu ratio was optimized to realize the highest catalytic activity for AB hydrolysis.…”
