Abstract To make the most of unique properties nanomaterials, and to bridge gap between fundamental applied research, controlled, green, cheap energy efficient syntheses nanoparticles are required. In this respect, room low temperature surfactant-free colloidal obtained in viscosity boiling point solvents, without additives or nature-derived extracts, promising develop more active (electro)catalysts. Recently, a synthesis gold has been documented ( Chem. Mater . 2023, 35, 5, 2173) that requires only water, base such as NaOH, an alcohol HAuCl 4 Unfortunately, nanomaterials often sensitive multiple parameters it is well acknowledged reproducibility general challenge chemical sciences, where no exception. Here, we investigate effect water conductivity solvent grade on (ca. 30 °C) alkaline mixtures ethanol water. The can be performed with relatively low-grade but high purity importance also stressed for ethylene glycol glycerol used source reducing agents. results study over 100 samples pave way greener, controlled scalable nanomaterials.

Copper-based catalysts have attracted enormous attention due to their high selectivity for C2+ products during the electrochemical reduction of CO2 (CO2 RR). In particular, grain boundaries on contribute generation various Cu coordination environments, which been found essential C-C coupling. However, smooth-surfaced Cu2 O nanocrystals generally lack ability surface reorganization form multiple and desired undercoordination sites. Flow chemistry armed with unparalleled mix reaction mixture can achieve a very concentration unstable intermediates, in turn are used up rapidly lead kinetics-driven nanocrystal growth. Herein, synthesis unique hierarchical structure numerous steps (h-Cu2 ONS) via flow chemistry-assisted modulation growth kinetics is reported. The h-Cu2 ONS underwent rapid reconstruction under RR conditions exhibit heterointerfaces between phases, setting preferable condition facilitate bond formation. Notably, obtained increased C2 H4 Faradaic efficiency from 31.9% 43.5% electrocatalysis concurrent morphological reorganization, showing role stepped surface. Also, demonstrated 3.8-fold higher ethylene production rate as compared nanocube.
