Herein, a heterogeneous hollow structured TiO2 decorated Pt nanoparticles were successfully designed and synthesized via hard-template approach and photo-deposition process toward TC photodegradation. The Pt nanoparticles loaded on the surface of hollow structured TiO2 can increase the visible light absorption due to the local surface plasmon resonance (LSPR) effect. Furthermore, owing to the tough electron oscillation of the LSPR excitation, the plasmonic hot holes on the surface of Pt nanoparticles can capture the electrons of TiO2, effectively facilitating the separation of photo-excited charge carriers because of the formation of Schottky junction constructed between Pt and TiO2. Combined the natural merits of shorten conveying path of charge carriers and physical structural stability for hollow structure, the optimal Pt/TiO2 hetero-junction hybrid showed superior photocatalytic activity and durability for TC photodegradation with the degradation efficiency of 93.8 % after 30 min and the rate constant of 0.09196 min−1 under 300 W Xe lamp irradiation.

Electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS) analyses confirmed that the pyrolysis of polydopamine (PDA) not only improves electrode conductivity but also contributes to the formation of a stable solid electrolyte interface (SEI). Additionally, SiOx undergoes disproportionation reactions during the pyrolysis of PDA, further the improves the cyclic stability of the composites.

Phase change latent heat stands out among various thermal storage methods due to the high energy density of phase change materials (PCMs). PCMs possess unique characteristics such as tunable thermal storage or/and release processes, constant phase-transition temperatures, and changes in physical state. However, solid-liquid PCMs cannot be directly utilized due to the liquid leakage in their melted state. The encapsulation of PCM microcapsules (PCMMs) is essential for overcoming limitations and optimizing functionalities of the PCMs. Encapsulation strategies play a key role in considering factors like morphology, structure, physicochemical properties, and specific applications. Furthermore, PCMMs can expand their potential applications by incorporating functional nano-materials within their shells or introducing specific components into their cores during the synthesis process. This review examines various encapsulation strategies for PCMMs, including physical, physicochemical, and chemical methods. Various applications of PCMMs are summarized and analyzed with regards to the characteristics of PCMs in thermal storage, temperature control, and state transformation. Furthermore, the reinforcement strategies or/and design considerations of PCMMs are crucial for meeting specific requirements, such as conventional latent heat storage, thermal protection, and thermal-triggered intelligent materials.
