Small molecule adsorption energy storage

What is adsorption based energy storage?

One type of energy storage system that is gaining popularity is adsorption-based energy storage such as adsorption thermal energy storage (ATES) also referred to as adsorption heat storage (AHS), a green technology that relies on the interaction between the surface of adsorbents and fluids as the adsorbates.

What is adsorption thermal energy storage?

Adsorption thermal energy storage Adsorption thermal energy storage (ATES) systems hold significant promise for improving the efficiency of energy storage and retrieval by utilizing the physicochemical processes of adsorbents.

How can adsorption energies be predicted?

Predicting adsorption energies of small molecules (e.g., OH, OOH, CO) on electrocatalysts involved in electrochemical reactions aids in accelerating the design and screening of electrocatalysts. Avoiding computationally expensive electronic structure calculations increases the speed of such predictions.

What is adsorption in chemistry?

Adsorption is the process of attracting and holding molecules of a gas or liquid onto the surface of a solid material [, , ]. The adsorption energy of a material is a critical parameter that determines its ability to store energy.

Why is adsorption energy important?

The adsorption energy of a material is a critical parameter that determines its ability to store energy. Accurately predicting the adsorption energy of a material can help researchers identify new materials that can be used for energy storage applications [19, 20].

Are adsorption energies a function of the electronic descriptor?
