“…Methanol, being a key product derived from the combination of carbon dioxide and solar energy, known as "liquid sunshine" (as shown in Figure 1), holds significant importance in addressing future energy and environmental challenges. DMFCs, with their high specific energy (up to 6000 Wh kg 1 for pure methanol), have shown remarkable commercialization potential in various applications, including backup power for laptops, power sources for individual soldiers, forklifts, unmanned aerial vehicles, and stationary power plants [18,19].

Nutrient resources account for an enormous quantity of the world’s waste materials. According to recent research, nuts and their byproducts are good for a variety of applications and are important natural resources for nutrition. Waste and nut residues in the environment could cause environmental problems. A critical issue is how this waste is employed in various applications. Nuts contain important chemicals that could be used to build catalytic nanomaterials. A variety of heterogeneous catalysts can be created directly from different parts of nuts, such as the shell, kernel, extracts, and so on, or they can be used as nanoparticle stabilizing and reducing agents. Nuts and their wastes can be particularly essential in evolution reactions, oxidation reactions, hydrolysis, pollutant degradation, and so on due to their extraordinary chemical properties. Natural substances such as biopolymers, zeolites, diatomites, agricultural wastes (such as rice husk, bagasse pith, coconut shell, and so on), and nut wastes are used to make inexpensive catalysts. This review focuses on the industrial benefits and future applications of these commercially feasible green resources to change, for the first time, the production of nanomaterials from nuts as environmentally friendly resources and their catalytic applications.

“…With regard to various categories of catalysts, materials based on precious and rare metals such as platinum, ruthenium, and their families have the highest efficiency in methanol oxidation but the high price of these catalysts is a challenge for the industrialization and commercialization of these methanol fuel cells [15,16]. Also, besides their intrinsic electrocatalytic properties for use in methanol oxidation, their acceptable electrochemical active surface and electrical conductivity are other merits.…”

This study provides the methanol oxidation capability of two nanocatalysts, CeO2-NiO (CN) and CeO2-NiO-rGO (CNR), synthesized by a cost-effective hydrothermal method. The synergistic effect of compositing CeO2-NiO with reduced graphene oxide was evaluated. These synergic effect makes a good electrochemical active surface area and suitable electrical conductivity for catalyst. In addition, rGO with good electrical conductivity revealed considerable improvement in the methanol oxidation reaction (MOR) performance of the catalyst. The cyclic stability measurements of CeO2-NiO-rGO showed a high retention ability of 96% in 500 consecutive CV cycles, while the stability of CeO2-NiO in the same number of cycles is about 93%. The complementary methanol oxidation process results indicated an oxidation current density up to 49.5 and 68.5 mA/cm2 for CN and CNR at a scan rate of 20 mV/s, respectively. The proposed catalyst can be considered as an attractive, stable, and inexpensive candidate in the field of methanol oxidation to use in methanol fuel cells.

Activated carbon based Cobalt nanoparticles (Co@AC NPs), considered in the context of hydrogen energy, which is a renewable and sustainable energy, were synthesized by the hydrothermal method, and their catalytic activities were tested. For this, hydrogen production tests were carried out with the help of sodium borohydride (NaBH4) methanolysis of Co@AC NPs synthesized by the thermal method. Ultraviolet–visible spectroscopy (UV–Vis), Fourier transmission spectroscopy (FTIR), transmission electron microscopy (TEM), and X-ray diffraction (XRD) characterization tests were performed. According to the TEM characterization result, it has been observed that the NPs have a spherical shape and an average size of 2.52 ± 0.92 nm. Then, using the catalytic studies, it was observed that hydrogen production’s reusability is found to be 86% . The activation energy (Ea), enthalpy (∆H), and entropy (∆S) values were found to be 20.28 kJ⋅mol−1, 17.74 kJ⋅mol−1, and −125.97 J⋅mol−1 K−1, respectively. The obtained values have yielded excellent results and guide future sustainable and renewable hydrogen energy studies by reducing costs, ensuring environmental sustainability by avoiding the formation of undesirable by-products, and producing hydrogen from NaBH4 through its high catalytic properties.
