Special Issue Information

Dear Colleagues,

The rational design and development of cost-efficient and highly active catalytic materials is currently one of the main research pillars in the field of heterogeneous catalysis. To this end, surface and interface engineering are among the most efficient strategies toward the fabrication of innovative and advanced catalytic materials. A prerequisite for this is a fundamental understanding of the structure–performance relationships at the (near-) atomic scale; these, however, remain a formidable challenge due to the complexity of heterogeneous catalytic processes. Recent progresses in nanosynthesis with uniform and well-defined structures, fine-tuning engineering strategies (size/shape control), in situ characterization techniques, and theoretical calculations have offered unique opportunities towards the fundamental understanding of surface and interface phenomena, which in turn could pave the way for the rational design of catalytic systems.

Herein, this Special Issue explores the recent experimental and theoretical advances toward the fundamental understanding of surface and interface phenomena in catalysis. In this regard, surface and interface engineering strategies, including crystal phase design, morphology/size engineering, aliovalent promotion/doping, etc., through the use of advanced synthesis/modification routes would be of great interest to this Special Issue. Moreover, advanced characterization and computation studies for unravelling the role of surface and interface sites and the establishment of reliable structure–property relationships are welcomed.

Non-noble metal electrocatalysts for the oxygen evolution reaction (OER) have recently gained particular attention. In the present work, a facile one-step electrodeposition method is applied in situ to synthesize cobalt sulfide nanostructures on nickel foam (NF) electrodes. For the first time, a systematic study is carried out on the impact of the Co/S molar ratio on the structural, morphological, and electrochemical characteristics of Ni-based OER electrodes by employing Co(NO3)2·6 H2O and CH4N2S as Co and S precursors, respectively. The optimum performance was obtained for an equimolar Co:S ratio (1:1), whereas sulfur-rich or Co-rich electrodes resulted in an inferior behavior. In particular, the CoxSy@NF electrode with Co/S (1:1) exhibited the lowest overpotential value at 10 mA cm−2 (0.28 V) and a Tafel slope of 95 mV dec−1, offering, in addition, a high double-layer capacitance (CDL) of 10.7 mF cm−2. Electrochemical impedance spectroscopy (EIS) measurements confirmed the crucial effect of the Co/S ratio on the charge-transfer reaction rate, which is maximized for a Co:S molar ratio of 1:1. Moreover, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF) were conducted to gain insights into the impact of the Co/S ratio on the structural and morphological characteristics of the electrodes. Notably, the CoxSy@NF electrocatalyst with an equimolar Co:S ratio presented a 3D flower-like nanosheet morphology, offering an increased electrochemically active surface area (ESCA) and improved OER kinetics.

One of the most significant challenges the world is currently facing is wastewater treatment. A substantial volume of effluents from diverse sources releases numerous pollutants into the water. Among these contaminants, organic pollutants are particularly concerning due to the associated risk of being released into the environment, garnering significant attention. Rapid advancements in agriculture and industry on a global scale generate vast volumes of hazardous organic compounds, which eventually find their way into natural systems. Recently, the release of industrial wastewater has been increasing, due to the progress of numerous businesses. This poses a danger to humans and the environment, leading to environmental contamination. The application of carbon nanocomposites in applied nanotechnology has recently expanded due to their large surface area, substantial pore volume, low preparation cost, and environmental resilience. Expanding the use of nanomaterials in water treatment is essential, as magnetic carbon nanocomposites consistently demonstrate an efficient elimination of pollutants from water solutions. In the current study, we have highlighted the application of magnetic porous carbon nanocomposites in removing organic pollutants from wastewater. Full article
