Transition metal layered double hydroxides (LDHs) have attracted much attention as catalysts due to their multiple valence states and high electrocatalytic activity. Traditional enzyme-based electrochemical H2O2 sensor is limited by short lifetime, instability, and complicated fabrication procedure, making it difficult to be widely used. Instead of natural enzymes, transition metal based LDHs can be applied as electrocatalysts for enzyme-free H2O2 sensor. In this work, CoZn-LDH nanosheets grown on CuO nanowires (NWs) were synthesized on carbon cloth (CC) by electrodeposition and hydrothermal methods for the electrochemical enzyme-free detection of H2O2. For this purpose, CuO NWs were first electrodeposited on CC substrate, on which CoZn bimetal LDH nanosheets were synthesized by the hydrothermal technique. Herein, CC provides an ideal conductive substrate for the growth of CuO NWs and CoZn-LDH, so that the sythesized CuO/CoZn-LDH NWs can be evenly dispersed, exposing more active sites for the enhancement of their electrocatalytic activity. As a result, CuO/CoZn-LDH NWs display excellent electrocatalytic activity for the reduction of H2O2. The fabricated sensor has a good linear response in the concentration range of 0.01–16 mM for the electrochemical detection of H2O2, with low detection limit of 0.46 μM and high sensitivity of 760.64 μA mM–1 cm–2. In real sample mouthwash detection, the proposed sensor demonstrates the efficient recovery of H2O2, indicating the ability of CuO/CoZn-LDH NWs to quantitatively detect real samples.

The release of radioactive iodine into the environment poses a significant threat, as it can contaminate soil, water, and food chains, leading to detrimental effects on ecosystems and biodiversity. Hence, employing the adsorption method proves to be a simple yet effective approach for treating radioactive waste. N/Ocodoped ultrathin porous biochar, synthesized from casein using NaHCO 3 activation, emerges as a potential candidate for adsorption materials. The saturation level of I 2 adsorption in 100 mg L −1 iodine−cyclohexane solution is 73 mg•g −1 at 20 min. The density functional theory (DFT) calculations and experiments attribute this phenomenon to the presence of graphite nitrogen (N G ) and C−OH groups on the biochar surface. Furthermore, the pseudo-first-order model fits better with the experimental values, suggesting that the adsorption of iodine by the adsorbent is primarily physisorption-based. The Freundlich isotherm is suitable for iodine adsorption of biochar, owing to the abundance of adsorption sites within the porous structure, particularly at the edges, which enhance the adsorption activity. Significantly, the study highlights that N G adsorptive sites exhibit 1.5 times higher adsorption activity compared to C−OH adsorptive sites, underscoring the essential role of N G in iodine adsorption for electron transfer. Overall, these findings underscore the potential of N/O-codoped ultrathin porous biochar in effectively mitigating the presence of radioactive I 2 , showcasing its promise in addressing environmental challenges associated with radioactive contamination.
