Predicting Accurate Adsorption Energies for Rational Catalytic Design via Machine Learning

Scientific Achievement

A machine learning method, DOSnet, was used to extract key features from the electronic density of states and provide accurate predictions of adsorption energies for catalysis.

Significance and Impact

DOSnet provides an electronic latent space, which can be freely explored without additional ab initio calculations, greatly accelerating materials discovery and design.

Research Details

A 1D convolutional neural network model was used to featurize the electronic density of states.
DOSnet can accurately predict adsorption energies with accuracies of ~0.1 eV when tested on a diverse dataset containing 2000 metal alloy surfaces and 11 adsorbate types.
