(1) thermal decomposition synthesis of iron oxide NPs and EDC-NHS coupling for complex synthesis: optimal research of loading capacity, superparamagnetism, spatial factors (steric hindrace & bulk diffusion & orientation);
(2) characterization and optimization of biocatalytic performance: activity, thermal stability, pH stability, kinetics and recycling stability.

(1) Analyzed the HER descriptors and design rules of nanostructures of 2D-layered catalyst materials: thermodynamically regulating the H-Metal interaction and kinetically lowering the barrier from water dissociation;
(2) Identified and analyzed the roles of different nanostructures and interfaces-like active sites (edge, basal), bulk conductivity and phases-in HER enhancement and further explored the weight of these roles for boosted performance.
(3) Output: Presentation 1: topic confirmation before experiments; Project Plan: retrieval, views and proposals; Presentation 2: topic investigations; Presentation 3: recent progress; Poster presentation.
(1) Investigated how adjusting parameters (T, chalcogen species and molar ratios, precursor ratios) will regulate the HER activity, kinetics and stability;
(2) Explored the contributions of structural morphologies in better activity revelation.
(1) Corresponded signal peaks (1S exciton Ground State Bleach and Charge Transfer signal) with kinetics by time-resolved transient absorption spectroscopy:
I. Size-dependent quantum confinement: how particle size affects signals and their kinetic curves in the single QD system;
II. The lifetime of 1S exciton: how junctions affect the annihilation kinetics of 1S exciton in QD-MO coupled system.
(2) Verified the size-rate dependence in the classic Marcus ET Theory (the existence of inverted regime);
(3) Analyzed the discrepancy between ET rate and device performance through photo-excited interband and intraband transitions.
(4) Output: oral presentation.

Bio: My major experience focuses on the revelation of underlying composition-structure-activity/property correlations of functional nanomaterials (nanostructured), including 2D-layered TMD-based HER electrocatalysts, quantum dots-based coupling system in solar cells. I attach importance to the intrinsic structural/morphological and electronic properties and modification with the corresponding optimized properties/behaviours. Another personal interest of mine is to predict and optimize the performance of nanomaterials with machine learning-assisted tools and operations.
