Kirkendall‐Effect‐Mediated Hollow Bimetallic Hexacyanoferrates for Aqueous Zn‐Ion Batteries: Suppressing Jahn–Teller Distortions and Enhancing Ion Transport and Cyclability

open access: yesCarbon Energy, EarlyView.
Kirkendall‐engineered hollow Ni–Mn hexacyanoferrates feature Ni‐tunable shell thickness and uniform alloying, coupling architectural control with electronic stabilization. Composition–morphology co‐optimization suppresses Mn³⁺‐driven Jahn–Teller distortions and lowers charge‐transfer barriers, enabling rapid Zn²⁺ transport and reversible redox.

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.
