Abstract Nano‐sized perovskites were synthesized in a spray flame from nitrate precursors dissolved ethanol and ethanol/2‐ethylhexanoic acid (2‐EHA) mixtures. Experiments with led to broad particle‐size distribution the formation of undesired phases such as La 2 CoO 4 , O 3 Co . The addition 2‐EHA can initiate micro explosions burning droplets has been systematically investigated toward single‐phase, high‐surface‐area LaCoO LaFeO narrow size distribution. To investigate effect 2‐EHA,...
LaMnO3+δ nanoperovskites were prepared via the continuous and scalable spray-flame synthesis (SFS) technique from metal nitrate-based solutions by using either ethanol (EtOH) as solvent or a mixture of (50 vol %) 2-ethylhexanoic acid (EtOH/2-EHA). Solutions based on pure EtOH generated several phases broad multimodal particle size distribution, which is attributed to combination gas-to-particle droplet-to formation particles. The product contained bimodal distribution orthorhombic (Pnma II)...
The product properties of mixed oxide nanoparticles generated via spray-flame synthesis depend on an intricate interplay solvent and precursor chemistries in the processed solution. effect two different sets metal precursors, acetates nitrates, dissolved a mixture ethanol (35 Vol.%) 2-ethylhexanoic acid (2-EHA, 65 was investigated for LaFexCo1-xO3 (x = 0.2, 0.3) perovskites.

Developing effective non-noble metal electrocatalysts for the oxygen evolution reaction (OER) remains challenging due to limited active sites and poor electronic conductivity in mixed oxide catalysts. To address these limitations, a one-step spray drying method is employed synthesize hierarchical La0.8Sr0.2CoO3 supraparticles (LSCO-SP) from high-surface-area nanoparticles (LSCO-NP). LSCO-SP demonstrate significantly enhanced OER performance, requiring ~300 mV lower overpotential at 100 mA...
Abstract In sodium-ion batteries (SIBs), TiO 2 or sodium titanates are discussed as cost-effective anode material. The use of ultrafine particles overcomes the effect intrinsically low electronic and ionic conductivity that otherwise limits electrochemical performance thus its Na-ion storage capacity. Especially, nanoparticles integrated in a highly conductive, large surface-area, stable graphene matrix can achieve an exceptional rate performance, durability, increase We report direct...
Abstract Despite considerable efforts to develop electrolyzers for energy conversion, progress has been hindered during the implementation stage by different catalyst development requirements in academic and industrial research. Herein, a coherent workflow efficient transition of electrocatalysts from basic research application readiness alkaline oxygen evolution reaction is proposed.

Metal sulfides are promising alternatives to noble metal electrocatalysts for water‐based hydrogen evolution. Pentlandites, notably, exhibit high activity in acidic environments. To explore their potential alkaline conditions, pentlandite electrodes tested both conventional three‐electrode setups and scaled up a 12.6 cm membrane electrode assembly (MEA). Optimized pentlandites with stochiometry of , containing Fe, Ni, Co, show reduced overpotentials evolution higher Fe Ni contents. However,...

In recent years, there has been a growing need for new renewable energy sources due to the rapid depletion of conventional and an escalating demand. Since environmental protection concerns are increasing, electrochemical processes becoming increasingly essential [1]. Specifically, focus shifted towards storing in hydrogen its subsequent conversion into on-demand electricity [2]. Here, hydrogen, generated via water electrolysis, serves as either intermediary generating carriers like liquid...
Trace organic pollutants including pharmaceuticals, industrial chemicals, pesticides, and personal care items pose considerable risks to the environment human health due their enduring nature, toxicity, tendency accumulate in biological systems [1,2].
