“…It needs ultralow overpotential of 20 mV and 132 mV to achieve 10 and 100 mA under the HER respectively. In 2020, it is reported from Zou, H.-H., et al's work [36] a photoelectrochemical (PEC) water splitting under the action of novel LTO/LaOCl@N-C microspheres heterostructures (MH) for hydrogen generation. The hold hybrid photocatalyst LTO/LaOCl@N-C (MH) exhibited outstanding PEC hydrogen evolution feature and as well as better durability when compared to the pure LTO material.…”

Materials engineering and catalysis are known as central sciences, which can deeply contribute to the technological development of our nations, and as well as ensure the environmental protection and cleaning from both organic and inorganic contaminants. So, the generation of the most wanted chemical and fuels such as (CH4) or to carbon monoxide (CO/H2), methanol (CH3OH) or even to hydrogen (H2) and ammonia (NH3) requires strongly active, selective, stable, and as well as reusable materials (catalysis) to fulfill the mankind needs. The determination and removing both inorganic and organic are highly regarded special issue in healthcare. So that, all these areas strong materials for the complete transformation of these chemical products. Indeed, zeolite materials are very explored in the recent years as they present advanced properties in both catalysis and environmental concerns. Also, its combination with transition noble and non-noble metals are also considered in order to boost the catalytic yields. In fact, here, it is ascribed the role of transition rare-earth (RE) elements in the hybrid materials engineering for advanced technological applications. It demonstrated that rare earth oxides might enhance catalytic features and avoid the loss of acid sites under the fluid catalytic craking (FCC) unit operation. Moreover, It is shown that (RE) elements might be used for materials engineering for high-tech uses such as in hydrogen evolution reaction (HER), methanol oxidation reaction (MOR), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). Many other reactions can be realized over hybrid materials made via the use of rare earth (RE) elements with improved catalytic performances. Therefore, due to the large properties of transition rare-earth (RE) metals, more possible superb materials will be engineered in upcoming generation.

“…Similarly, Zou et al also put forward their own views. [ 78 ] A novel heterostructure of LaCP microspheres was prepared by MSM using LTO/LaOCl@N‐C microspheres as precursors and templates. As a reaction medium, sodium chloride not only promoted the establishment of heterostructures but also participated in the reaction process as an important reaction intermediate.…”

Most of the photocatalytic materials are prepared by wet chemical methods and calcination methods. These preparation methods usually have the problems of slow reaction speed and low crystallinity of products, which seriously restrict the development of photocatalytic technology. Molten salt method (MSM) has attracted much attention of researchers because of its unique advantages in optimizing the synthesis route of photocatalyst. Herein, the application of molten salt technology in the preparation of photocatalytic materials in recent years is summarized. The advantages of MSM in photocatalytic synthesis, such as promoting crystallization, adjusting morphology, accelerating the construction of heterostructure, stabilizing single atom, doping auxiliary elements and adjusting defect position, are also discussed in detail. It is indicated that MSM has important application potential in the preparation of photocatalytic materials. Meanwhile, the research achievements and existing problems of MSM are summarized, and suggestions for further application of MSM in photocatalyst's preparation are put forward.

“…So the molten salt method was chosen for calcination, which helps to achieve phase-pure products with uniform powder properties and controlled size/shape at relatively low temperatures compared to the conventional high-temperature solid-phase method. 21 It is a new attempt to better control the morphology of precursors and improve the thermal stability of TiO 2 by adopting a core–shell structure of spherical SiO 2 @TiO 2 . Since Cu-PDACP does not have a homogeneous morphology, the calcination process may have an inhomogeneous contact, resulting in an incomplete reaction.…”
