RF Sputtering of ZnO (002) Thin Films on Top of 3C-SiC-on-Si (100) Substrates for Low Cost Piezoelectric Devices

Ni Nanoparticles Supported on High Surface Area Carborundum for Enhanced Hydrogen Production by Ammonia Decomposition

“…Similar effects on Ni-based catalysts, such as Ni/MMT and Ni/CaO-Al 2 O 3 , have also been reported in the past. Heat treatment would cause Ni species to aggregate, which is detrimental to the catalytic activity. , At the same time, it was observed that the peak at 35.6° decreased gradually with the calcination temperature, which can be credited to the presence of porosity Figure S2 depicts the XRD pattern of the reduced 30Ni/SiC-700, which lacks any NiO identifying peaks.…”

Instead, three additional peaks are seen at 2θ = 44.5, 51.9, and 76.3°that are thought to be metal Ni species.…”
