Temperature-Induced Reorganization of Supported Zn Clusters on Cu(111): From Minimum-Energy Structures to Finite-Temperature Ensembles
Jiayan Xu, Zheng Yu, Abhirup Patra +4
Understanding the nature of catalytic active sites under reaction conditions remains a central challenge in heterogeneous catalysis. In industrial copper/zinc oxide/alumina catalys…
Benchmarking Universal Machine Learning Interatomic Potentials for Supported Nanoparticles: Decoupling Energy Accuracy from Structural Exploration
Jiayan Xu, Abhirup Patra, Amar Deep Pathak +3
Supported nanoparticle catalysts are widely used in the chemical industry. Computational modeling of supported nanoparticles based on density functional theory (DFT) often involves…
Experimental and Computational Demonstration of a Highly Stable, in-situ Pt Decorated Sputtered ZnO Hydrogen Sensor for sub-ppm Level Detection
Puja Ghosh, Pritam Ghosh, Rizwin Khanam +7
In this work, we present a Pt decorated ZnO thin film-based gas sensor for hydrogen detection, fabricated using a sputtering technique and an in-situ Pt decoration approach. Specif…
Dynamic Metal-Support Interaction Dictates Cu Nanoparticle Sintering on AlO Surfaces
Jiayan Xu, Shreeja Das, Amar Deep Pathak +4
Nanoparticle sintering remains a critical challenge in heterogeneous catalysis. In this work, we present a unified deep potential (DP) model for Cu nanoparticles on three AlO$_…
