Special Issue Information

Dear Colleagues,

The increasing global demand for clean water and fresh air has driven significant research efforts toward developing efficient catalytic materials, such as metal oxides, perovskites, MOFs, COFs, and carbon-based catalysts etc., for environmental remediation. Catalytic processes play a crucial role in addressing water and air pollution by enabling sustainable and energy-efficient degradation of contaminants, including volatile organic compounds (VOCs), nitrogen oxides (NOx), carbon monoxide (CO), and emerging pollutants. Recent advances in catalytic oxidation, photocatalysis, photothermal catalysis, and advanced oxidation processes (AOPs) have opened new avenues for enhancing reaction kinetics, selectivity, and energy efficiency in water and air treatment technologies.

This Special Issue, “Recent Advances in Catalytic Materials for Water and Air Treatment”, aims to showcase cutting-edge research on catalytic materials and their applications in wastewater treatment and air pollution control. We welcome contributions that explore novel catalyst design, reaction mechanisms, and performance optimization for the removal of organic/inorganic pollutants, greenhouse gases, and toxic gases.

In summary, this Special Issue will serve as a platform to highlight transformative advances in catalytic material design and their practical applications, to accelerate the development of next-generation catalytic technologies for sustainable water and air purification.

Abstract
In this study, a highly efficient graphitic carbon nitride/graphene oxide (X kGy-g-C3N4/GO, X: mean different irradiation dose of 200, 300, 400, and 500 kGy) adsorbent was successfully prepared by electron beam irradiation method (EBR) and used for the adsorption [...] Read more.
In this study, a highly efficient graphitic carbon nitride/graphene oxide (X kGy-g-C3N4/GO, X: mean different irradiation dose of 200, 300, 400, and 500 kGy) adsorbent was successfully prepared by electron beam irradiation method (EBR) and used for the adsorption of ofloxacin (OFL). Structure and morphology characterization results confirmed the successful composite of g-C3N4 and GO through EBR. The effects of various conditions on the adsorption capacity, including irradiation dose, pH, adsorbent dosage, and initial OFL concentration were analyzed in detail through experiments. Results indicated that 400 kGy-g-C3N4/GO exhibited the maximum adsorption capacity for OFL (222.0 mg·g−1), and the adsorption performance was affected by pH through electrostatic interactions, reaching optimum at pH = 7.0. Coexisting ion experiments revealed that CO32− reduced OFL adsorption capacity. The adsorption isotherm and kinetics were best described by the Langmuir model (R2 = 0.984) and pseudo-second-order model (R2 = 0.995), respectively. Thermodynamic studies of adsorption indicated a spontaneous and exothermic in adsorption process (∆G0 = −25.21, ∆S0 = 0.050, and ∆H0 = −10.25). This research provides a fresh approach to the reasonable design of g-C3N4/GO composites as adsorbent with potential applications in OFL wastewater treatment. Full article
