Auto-combustion synthesis of perovskite-type oxides SrTi1−xFexO3−δ [PDF]

, 2015
A versatile one-pot auto-combustion method for the synthesis of powders of iron-doped strontium titanate, SrTi1−xFexO3−δ, has been developed. The synthesis is optimized by the combined use of EDTA and citric acid as chelating agents, and an appropriate ...

LiCrxFeyMn2−x−y−zTizO4 Spinels as Cathodes for Li‐Ion Batteries: A Multidoping Approach to Suppress Jahn–Teller Distortion

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Multidoping of spinel LiMn2O4 with Cr, Fe, and Ti effectively suppresses Jahn–Teller distortion, enhancing structural stability and cycling performance in Li‐ion batteries. Operando X‐ray absorption spectroscopy and ex situ X‐ray diffraction confirm a stable spinel framework and indicate Mn as the only electrochemically active element.

Decoupling Size and Electronic Effects in Doped SrTiO3 Photocatalysts Through Surface Area–Normalized CO2 Hydrogenation Rates

Advanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
Exploring the photocatalytic reverse water–gas shift (RWGS) reaction on doped SrTiO3 nanoparticle films, reveals that normalizing catalytic rates by the catalyst's specific surface area (SSA) disentangled surface area effects from the catalyst's intrinsic material properties.

A Novel Supercapacitor with Integrated Photosensitive Electrode to Enhance Its Capacitance Under Solar Light

Small, Volume 22, Issue 13, 3 March 2026.
In this research we demonstrated that the energy density of supercapacitors can be enhanced at about 50% by generating extra charge through the use of a photosensitive cell coupled to the supercapacitor estructure. ABSTRACT This research reports a supercapacitor (SC) made with a photosensitive electrode (composed of LaFe0.94V0.01Mn0.05O3 (V‐LFO ...
