Green and sustainable use of macadamia nuts as support material in Pt-based direct methanol fuel cells
The successful commercialization of direct methanol fuel cells (DMFCs) is hindered by inadequate methanol oxidation activity and anode catalyst longevity. Efficient and cost-effective electrode materials are imperative in the widespread use of DMFCs. While Platinum (Pt) remains the primary component of anodic methanol oxidation reaction (MOR) electrocatalysts, its utilization alone in DMFC systems is limited […]
Effects of cashew nutshell ash on the thermal and sustainability properties of cement concrete.
The present study valorizes cashew nutshell ash (CNA) and uses it at 5-20 wt. % of cement for concrete production. The concrete grades of 25-40 MPa were used as mix design proportions. The thermal and mechanical properties of the concrete samples were determined on day 28 of curing. Regression models were used to predict the […]
Presence of activated carbon particles from waste walnut shell as a biosorbent in monoethanolamine (MEA) solution to enhance carbon dioxide absorption
Greenhouse effects are a natural phenomenon that plays a high role in shaping the climate system. In this research, MEA solution was used for CO2 capture in presence of activated carbon particles from waste walnut shells as a biosorbent. The process parameters including temperature, pressure, MEA concentration, and activated carbon were used in the central […]
Iron-modified activated carbon derived from agro-waste for enhanced dye removal from aqueous solutions.
Background and aim: Finding a cost-effective adsorbent can be an obstacle to large-scale applications of adsorption. This study used an efficient activated carbon adsorbent based on agro-waste for dye removal. Methods: Pistachio shells as abundant local agro-wastes were used to prepare activated carbon. Then, it was modified with iron to improve its characteristics. Acid red 14 was […]
