Tackling the problem of 'having a closet full of clothes but nothing to wear', Smart Closet emerged in recent years as a digital closet assistant. This study investigates Chinese consumers' adoption intention toward Smart Closet from a perspective of psychological needs and motivations, integrating the Technology Acceptance Model and Self-Determination Theory. A total of 346 data was collected via an online survey. Structural equation modelling was used to test the proposed hypotheses. Results indicated that two of the three basic psychological needs (autonomy and relatedness) had positive impacts on consumers' motivational perceptions (usefulness and enjoyment) of Smart Closet, which in turn, positively influenced their adoption intention. Additionally, consumers' fashion consciousness was found to have moderating effects on the adoption process. This paper not only lends managerial implications to practitioners pertaining to the implementation of Smart Closet, also provides a reference for validating the integrated framework of TAM and SDT.

Inspired by natural photosynthesis, two-dimensional van der Waals (vdW) heterostructures are considered as promising photocatalysts for solar-driven water splitting and they attract ever-growing interest. A type-II vdW hetero-photocatalyst (CdTe/B4C3) integrating the polarized CdTe into metal-free B4C3 was constructed, which could achieve solar-driven spontaneous overall water splitting at pH = 0–7 and exhibit a high solar-to-hydrogen (STH) efficiency of 19.64%. Our calculation results show that the interlayer interaction between the CdTe and B4C3 monolayers in the heterostructure creates an interfacial electric field enhanced by the intrinsic dipole of polarized CdTe, which accelerates the effective separation of photogenerated carriers and makes the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) take place separately on the B4C3 and CdTe layers. Furthermore, the CdTe/B4C3 heterostructure has decent band edge positions to promote the redox reaction to decompose water due to the significant electrostatic potential difference in the CdTe/B4C3 heterostructure and it could trigger spontaneous redox reaction under light at pH = 0–7. This work is helpful for us to design type-II heterojunction photocatalysts with high efficiency of photogenerated carrier separation for overall water splitting. [ABSTRACT FROM AUTHOR]

The catalytic field aims to decrease reaction barriers, accelerate reaction processes, and enhance the selectivity toward a target product. This study uses first-principles calculations to design a modified direct Z-scheme SnS 2 /β-As heterostructure as a potential photocatalyst for overall water splitting. Our previous investigations have demonstrated that the SnS 2 /β-As heterostructure can realize a hydrogen evolution reaction (HER) under light, while the oxygen evolution reaction (OER) follows a pathway involving the intermediate HOOH*. Interestingly, by substituting an S atom of SnS 2 with a Se or Te atom, the rate-determining step of the OER is significantly reduced from 3.76 eV to 2.56 or 2.22 eV. Moreover, the OER can occur directly without the transition via HOOH*. Isoelectronic doping effectively trades off the adsorption strength of OER intermediates and promotes the OER process. This work highlights the dual benefits of isoelectronic doping, namely lowering the reaction barrier of the rate-determining step and promoting the selectivity of end products. These findings provide insights into the rational design of high-efficiency photocatalysts for water splitting.
