Herein, it is demonstrated that cobalt phthalocyanine (CoPc) adsorbed on nitrogen-doped mesoporous carbon (NMC) can serve as an efficient catalyst for ARPs. The CoPc-NMC composite stands out for its remarkable ability to reduce hexavalent Cr(<small>VI</small>) using formic acid as the reducing agent. This exceptional performance is attributed to the distinct characteristics of the composite, including atomically dispersed CoPc and strong π–π interactions with the rich pyridinic N-doped carbon support. It also reveals the complex involvement of active species, such as electrons and hydrogen radicals, which clarifies the mechanism behind this catalytic process.

Nevertheless, ongoing research efforts aim to address these challenges and unlock their full potential for sustainable photocatalysis. In this study, we have developed sp<small>²</small> carbon-linked and imine-linked 2D donor–acceptor CzTA-PDAN and CzTA-PDA COPs. Notably, the sp<small>²</small> carbon-linked CzTA-PDAN COP demonstrates superior charge separation, rapid photocurrent response, and excellent chemical stability compared to the imine-linked CzTA-PDA COP, owing to its fully conjugated robust structure. The band gap calculated from the Kubelka–Munk plot was 2.30 eV and 2.53 eV, respectively, which resulted in the sp<small>²</small>c CzTA-PDAN COP having a higher electron carrier transport efficiency. Leveraging its favorable photo and optoelectronic properties, we employed the CzTA-PDAN COP for the photocatalytic degradation of organic toxic dyes, rhodamine B and Rose Bengal, under 18 W white CFL illumination for 80 minutes and 390 minutes, respectively. Additionally, the sp<small>²</small> carbon-linked CzTA-PDAN COP exhibited exceptional degradation performance even under sunlight, achieving complete degradation of the RhB dye within 60 minutes of irradiation. This highlights the practical applicability and versatility of the CzTA-PDAN COP in environmental remediation scenarios.

Recently, two-dimensional transition metal dichalcogenides (2D TMDs), such as the pure 2D monolayer MoTe<small>₂</small>, MoS<small>₂</small>, WS<small>₂</small>, <em>etc.</em> TMDs, have become attractive materials for the HER. Using the first principles-based hybrid density functional theory (DFT) method, we have computationally designed a pure 2D monolayer MoTe<small>₂</small> TMD and examined its structural and electronic properties with electrocatalytic efficacy towards the HER. A non-periodic finite molecular cluster model Mo<small>₁₀</small>Te<small>₂₁</small> system has been employed to explore the feasibility of both the Volmer–Heyrovsky (V–H) and Volmer–Tafel (V–T) reaction mechanisms for the HER.
