“…The CO 2 conversion (X CO2 ), methane selectivity (S CH4 ), and methane yield (Y CH4 ) were calculated by the following equations 54 : where, n CO2, in and n CO2, out are the molar flow rates (mol s −1 ) of CO 2 at the reactor's inlet and outlet, respectively. Additionally, n CH4, out is the molar flow rate (mol s −1 ) of CH 4 at the reactor's outlet.…”

“…Because of its unique features for a range of applications in lucrative domains such as electro- 53 , basic-, and photocatalysis 53 , supercapacitor 54 , energy storage 55 , conversion 56 , and sensing 57 , MCN has long attracted the curiosity of specialists. Following that, even though MCN has been extensively investigated and demonstrated to have a perfect performance in the field of photocatalytic CO 2 conversion due to its unique properties in addition to its semiconductivity, mesoporous carbon nitride (gmp-C 3 N 4 ) has not been extensively studied in the thermal hydrogenation of CO 2 58 .…”

The CO2 methanation technique not only gives a solution for mitigating CO2 emissions but can also be used to store and convey low-grade energy. The basic character and large surface area of mesoporous carbon nitride, (MCN), are considered promising properties for the methanation of CO2. So, a series (5–20 wt.%) of Ni-doped mesoporous carbon nitride catalysts were synthesized by using the impregnation method for CO2 methanation. the prepared catalysts were characterized by several physicochemical techniques including XRD, BET, FT-IR, Raman spectroscopy, TEM, TGA analysis, Atomic Absorption, H2-TPR, and CO2-TPD. The catalytic performance was investigated at ambient pressure and temperature range (200–500 °C) using online Gas chromatography system. The prepared catalysts showed good performance where 15%Ni/MCN exhibited the best catalytic conversion and methane yield with 100% methane selectivity at 450 °C for investigated reaction conditions.

“…However, they undergo insulation and high cost. Some metal oxides, metal sulphides and metal phosphates which are battery type electrode materials suffer from inferior stability due to charge discharge processes [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Therefore, it is important to design specific architectures and develop new materials that combine the best properties of various components to create high-performance electrode materials.…”

In the world of energy storage devices, Supercapacitors occupy a very unique and pivotal position. Their rapid rate of discharge gives them high power density. They have high reversibility and are robust to a large number of charging and discharging cycles. Sustained research has revealed a certain set of properties and behaviour, that every prospective candidate supercapacitor material must possess. Metal organic frameworks (MOFs) with unique textural properties, excellent specific surface area, tuneable porous structure and distinctively advantageous electrochemical behaviour are prominent candidates for the use in energy storage applications. However pristine MOF based materials are handicapped due to their low conductivity and poor mechanical stability. These inherent deficiencies can be overcome by hybridizing pristine MOFs with other materials like carbon materials (Activated Carbon, Graphene and Carbon Nano Tubes), conducting polymers, metals, and small molecules through variety of methods. This review puts the spotlight on the utilization, growth and various forms of hybrid materials based on MOFs for supercapacitor applications. It also highlights the various surface engineering techniques on the materials for high potential applications.
