Role of sublimation kinetics of ammonia borane in chemical vapor deposition of ...
Sompalle, Balaji; Liao, Chun-Da; Wei, Bin; Cerqueira, Maria de Fátima; Nicoara, Nicoleta; Wang, Zhongchang; Sadewasser, Sascha; Alpuim, P.Hexagonal boron nitride (h-BN) is a critical 2D insulator used as a substrate, gate dielectric, or encapsulation layer for graphene and other 2D materials and their van der Waals heterostructures. It is also promising as an active layer in single-photon emitters and other photonic devices. With the chemical formula H3N-BH3, ammonia borane is the most attractive precursor for up-scalable growth of large-area h-B...
Bifunctional porous cobalt phosphide foam for high-current-density alkaline wat...
Li, Yue; Wei, Bin; Yu, zhipeng; Bondarchuk, Oleksandr; Araujo, Ana; Amorim, Isilda; Zhang, Nan; Xu, Junyuan; Neves, Isabel C.; Liu, LifengAlkaline water electrolysis is a cost-effective approach to hydrogen production, but it suffers from low operational current densities (typically ⤠500 mA cm-2) and thereby a low hydrogen production rate. Herein, we report the fabrication of self-supported porous cobalt phosphide (Co-P) foam by electrochemical anodization of commercially available cobalt foam, followed by thermal oxidation and subsequent phosp...
