Because CdO and Co form a covalent bond, Co interacts more strongly with O than Zn. In order to reduce nanoparticle crystallinity, oxygen defects improve the interaction between −O and oxygen defects in the lattice. From SEM micrographs, it appears that CdO does not completely change under the influence of dopants. It can be seen from the SEM image that both materials have very tightly packed particles. The Co and CdO dopants in ZnO nanocomposites prevent them from absorbing a large range of visible wavelengths. It is more energy-dense for nanocomposites with 5.28 eV to compare to 5.14 eV nanocomposites. The fact that CdO matrix has a tuneable bandgap is evident since different types of dopants are used in its manufacture. There are at least three distinct absorption modes in Co nanocomposites doped with CdO, around 450, 498, and 676 cm⁻¹.

The palm-shells are an agricultural waste from betel-nut production, an important economic crop in several regions around the world. The conversion process mainly involves pulverization, ZnCl₂-activation, and carbonization. The effect of carbonization temperatures – 500, 600, 700, and 800 °C, was studied on the properties of the activated carbon. Microstructural characterizations like BET, Raman, and XPS were carried out. All the activated samples are microporous, have a specific surface area &gt;1,000 m² g⁻¹, and possess an intensity ratio of D-to-G band close to 1. More than 80 % of the atomic concentration of the samples is carbon; the C 1s bonds include C=C or sp², C–C or sp³, C–(O,N), C=O, and O–C=O or π– π*. The activated carbon synthesized at 700 °C shows the most favorable properties for being used as the electrode in supercapacitors. Its electrochemical properties, evaluated by galvanostatic charge–discharge and cyclic voltammetry deliver the maximum specific capacitances of 144.48F·g⁻¹ at 1 A·g⁻¹ and 169.21F·g⁻¹ 20 mV·s⁻¹, respectively.

H₂-TPR confirmed that palladium oxide was reduced, and nickel oxide species strongly interacted with the CeO₂ support. The Ce³⁺ concentration determined by XPS showed that all catalysts surface contained the Ce reduced state. The catalysts showed a similar BET surface area, with 4Pd–Ce presenting the lowest value due to particle aggregation, which was confirmed from the EDS mapping analysis. Butadiene conversion consistently increased with temperature (40 °C–120 °C) until full conversion was reached on all the Pd catalysts while the maximum conversion on the 4Ni-Ce catalyst was 88 % at 120 °C.

With the possibility of long-term energy storage and re-electrification, hydrogen promises to promote the effective utilization of renewable and sustainable energy resources. Clean hydrogen can be produced through a renewable-powered water electrolysis process. Although alkaline water electrolysis is currently the mature and commercially available electrolysis technology for hydrogen production, it has several shortcomings that hinder its integration with intermittent and fluctuating renewable energy sources. The proton exchange membrane water electrolysis (PEMWE) technology has been developed to offer high voltage efficiencies at high current densities. Besides, PEMWE cells are characterized by a fast system response to fluctuating renewable power, enabling operations at broader partial power load ranges while consistently delivering high-purity hydrogen with low ohmic losses. Recently, much effort has been devoted to improving the efficiency, performance, durability, and economy of PEMWE cells. The research activities in this context include investigations of different cell component materials, protective coatings, and material characterizations, as well as the synthesis and analysis of new electrocatalysts for enhanced electrochemical activity and stability with minimized use of noble metals. Further, many modeling studies have been reported to analyze cell performance considering cell electrochemistry, overvoltage, and thermodynamics. Thus, it is imperative to review and compile recent research studies covering multiple aspects of PEMWE cells in one literature to present advancements and limitations of this field. This article offers a comprehensive review of the state-of-the-art of PEMWE cells.

In order to improve thermoelectric power generation, this work intends to construct and assess a hybrid system that combines Heating, Ventilating, and Air Conditioning (HVAC) condenser airflow with waste heat from diesel generator exhaust gases. The suggested system presents a new architecture that makes simultaneous use of condenser air and diesel exhaust, two easily accessible but infrequently coupled thermal sources and sinks. Compared to conventional setups, this method greatly increases TEG efficiency by taking advantage of high temperature differentials and passive sink flow. To mimic the behavior of the system under various operating situations, we developed a comprehensive thermal model. The effect of TEG plate dimensions, duct heights, and the TEG thickness-to-thermal-conductivity ratio (t/k) on temperature gradients and power output were investigated parametrically. The findings indicate that while larger cooling loads from the HVAC system result in worse performance, increasing the generator load and t/k ratio increases power output. With duct height = 0.04 m and a 5 m × 0.2 m TEG plate, the optimized arrangement produced a peak output of 4745 W, which translates to a 2.37 % increase in fuel efficiency.
