Summary: This study investigates the stochastic feature evolution in photocatalytic systems and proposes a statistical model to describe the uncertainties of light absorption, charge carrier migration, and surface reaction. The results show that the density distribution of surface electrons changes from skewed to approximately uniform distribution with increasing incident photon density. The rate-determining step of surface reactions shifts from charge carrier kinetics to reactant activation processes with the rise in system temperature. By optimizing the operational parameters and active site density, the electron-capturing probability of active sites can be significantly increased. The established model is validated by experimental photoactivity results.

Summary: This study proposes bionic phase change material (PCM) capsules that mimic the internal and external structure of chloroplast-granum, demonstrating significantly faster heat storage compared to sphere type capsules. The improvement is attributed to the bionic folded shape and inner membrane structure, which enhance heat convection and facilitate heat conduction. Furthermore, the capsules are filled into the packed-bed in a staggered arrangement, increasing heat transfer area and enhancing disturbance flow. As a result, the melting time is reduced by 33.2% and average exergy storage rate and efficiency are enhanced by 48.4% and 8.3%, respectively.
