“…Carbon materials with specific morphological features (e.g., mono/multidimensional, porosities, multilayers, and branches) and compositional merits (e.g., doped atomically with metals/non-metals, single atoms, and functionalized with metal nanoparticles) [ 121 , 122 , 123 , 124 , 125 , 126 , 127 ] could enhance CMD significantly due to their low cost, outstanding physical–chemical–thermal stability, and massive active sites. 3D metal organic framework [ 128 ], carboxylated carbon [ 129 ], or carboxylated graphene [ 130 ] materials as well as biomass-derived porous nitrogenized carbon [ 131 ] and graphdiyne [ 132 ] can also be good candidates for CMD.…”

Catalytic methane decomposition (CMD) is a highly promising approach for the rational production of relatively COx-free hydrogen and carbon nanostructures, which are both important in multidisciplinary catalytic applications, electronics, fuel cells, etc. Research on CMD has been expanding in recent years with more than 2000 studies in the last five years alone. It is therefore a daunting task to provide a timely update on recent advances in the CMD process, related catalysis, kinetics, and reaction products. This mini-review emphasizes recent studies on the CMD process investigating self-standing/supported metal-based catalysts (e.g., Fe, Ni, Co, and Cu), metal oxide supports (e.g., SiO2, Al2O3, and TiO2), and carbon-based catalysts (e.g., carbon blacks, carbon nanotubes, and activated carbons) alongside their parameters supported with various examples, schematics, and comparison tables. In addition, the review examines the effect of a catalyst’s shape and composition on CMD activity, stability, and products. It also attempts to bridge the gap between research and practical utilization of the CMD process and its future prospects.

“…Furthermore, g-C3N4 compounds are also employed as reducing agents to combat air pollution emitted by industrial plants. They serve as catalysts in the CO/CO2 conversion process [24][25][26][27], effectively reducing the levels of toxic gases in the atmosphere. This application contributes to the mitigation of harmful emissions and helps maintain air quality.…”

In this research, the researchers successfully fabricated photocatalysts hybrid materials using g-C3N4 microrods and g-C3N4 nanosheets, which were coated on water hyacinth cellulose sponges. The optical properties of the photocatalysts hybrid materials, specifically the g-C3N4 microrods and g-C3N4 nanosheets, were analyzed using a UV-vis spectrometer. The morphology of the g-C3N4 microrods and g-C3N4 nanosheets photocatalysts was examined using different procedures, including FTIR (Fourier-transform infrared spectroscopy), XRD (X-ray diffraction), and TEM (transmission electron microscopy). The results obtained from the study indicate that g-C3N4 microrods exhibited a higher level of crystallinity or orderliness in terms of intramolecular orientation compared to g-C3N4 nanosheets. This suggests that the microrods possessed a more organized arrangement of atoms within the material structure. Furthermore, the energy bandgap values, as determined from the study, were found to be 2.25 eV for the microrods and 2.75 eV for the nanosheets. As part of this project, the photocatalysts, namely g-C3N4 microrods and g-C3N4 nanosheets, were utilized as coating materials for water hyacinth-synthesized cellulose sponges. This process led to the formation of hybrid materials known as g-C3N4 MCS (Microrods Cellulose Sponge) and g-C3N4 NCS (Nanosheets Cellulose Sponge). The efficiency and reaction rate of MB removal were then studied with various models such as First order reaction, Second order reaction, Pseudo first order reaction, Pseudo second order reaction and Elovich model. The results obtained from the research project indicated that the g-C3N4 NCS hybrid material exhibited a notably higher rate of organic degradation compared to the g-C3N4 MCS hybrid material. In conclusion, this research project successfully achieved the fabrication and characterization of a photocatalysts hybrid material using cellulose sponge from water hyacinth. The material demonstrated excellent performance as an absorbent and degradation agent for organic pollutants in water, highlighting its potential for practical applications in water treatment and environmental remediation.

Titanium carbide (Ti3C2Tx) MXene possesses various unique physicochemical and catalytic properties.However, the electrochemical CO oxidation performance is not yet addressed experimentally. Herein, Ti3C2Tx (TX=OH, O, and F) ordered and exfoliated two-dimensional nanosheets ornamented with semispherical pallidum nanoparticles (2.5 Wt. %) with an average diameter of (10 ±1 nm) (denoted as Pd/Ti3C2Tx) is rationally designed for the electrochemical CO oxidation. The fabrication process is based on the selective chemical etching of Ti3AlC2 and delamination under sonication to form Ti3C2Tx nanosheets that are used as a substrate and reducing agent for supporting in situ growth of Pd nanoparticles via impregnation with Pd salt. Interestingly, Pd-free Ti3C2Tx displayed inferior CO oxidation activity, while Pd/Ti3C2Tx enhanced the CO oxidation activity substantially. This is attributed to the combination of outstanding physicochemical properties of Ti3C2Tx and the catalytic merits of Pd nanoparticles.
