Oleic acid induced tailored morphological features and structural defects in CuO for multifunctional applications

Abstract

Synergistically tuned noble metals and intentionally formed complex heterostructured nanomaterials can enhance the required application effectiveness but at the cost of tedious synthesis routes, expensive chemicals, and sophisticated instruments. To...

The role of surface oxides and stabilising carboxylic acids of copper nanoparticles during low-temperature sintering

“…Joshi et al reported minor fraction of Cu 64 O phase could be found in CuO nanoarchitectures which was determined by XRD. 35 Carbon nanotube–Cu 8 O and Cu 64 O composites have been proposed by Kim, et al 36 Mixed films of CuO and Cu 64 O was reported by Mohamed et al 37 We have also found Cu 64 O phases on the gelatine-stabilised copper fine particles collected under nitrogen atmosphere. 38…”

“…33 The crystal structure of Cu 64 O has been reported in the literature. 33,[35][36][37][38][39] The obtained particles were re-dispersed into DPG by premixing with a planetary centrifuge mixer and milling with zirconia beads (30 mm). The optimised milling conditions found in this study were 1000 rpm for 30 min and 2000 rpm for 30 min.…”

“…Not only Cu 2 O and CuO but also crystalline structures of metaphases, such as Cu 8 O and Cu 64 O were reported so far. [33][34][35][36][37][38][39] Therefore, the control of surface conditions of copper particles is highly important for sintering. Joshi et al reported minor fraction of Cu 64 O phase could be found in CuO nanoarchitectures which was determined by XRD.…”
