## Description

- description: 'The Zn0.5Cd0.5S semiconductor is widely recognized as a promising
    photocatalyst due to its strong light absorption capability and high conduction
    band potential, enabling the conversion of CO2 and H2O into syngas (CO and H2).
    However, its catalytic efficiency is significantly limited by the lack of active
    sites, restricting the simultaneous evolution of CO and H2. In this study, Cu2+
    and Ni2+ are co-introduced into Zn0.5Cd0.5S nanoparticles as active sites to selectively
    promote the evolution of CO and H2, respectively, thereby synergistically enhancing
    the photocatalytic activity for overall syngas production. The Zn0.5Cd0.5S photocatalysts
    incorporating Cu2+ and Ni2+ dual active sites were synthesized via a simple precipitation
    method. Experimental results demonstrate that Cu2+ active sites significantly
    enhance CO yield, whereas Ni2+ active sites improve H2 production. Theoretical
    calculations reveal that Cu2+ and Ni2+ play distinct roles in the reaction mechanisms:
    Cu2+ acts as the active site for CO2 reduction, markedly reducing the Gibbs free
    energy barrier for intermediate adsorption, while Ni2+ serves as the active site
    for hydrogen evolution in water splitting, facilitating H* adsorption. The synergistic
    effect of Cu2+ and Ni2+ significantly enhances the photocatalytic performance
    of Zn0.5Cd0.5S in syngas production. This study provides a facile strategy for
    active site modulation to tailor photocatalytic behaviour, offering insights into
    the rational design and synthesis of highly efficient photocatalysts for syngas
    production.'
