Abstract

The TiO2/Ti electrode was successfully synthesized by combining element N and metal Ni on the TiO2 matrix to degrade the organic compound Congo Red under UV-visible radiation. The aim of this study is to obtain Ni@N-TiO2/Ti electrodes and test their performance in degrading Congo Red dye under UV-visible light radiation. The Ni@N-TiO2/Ti electrode was prepared using the Sol-Gel and electrodeposition methods. The presence of nitrogen in N-TiO2 is determined by FTIR and detected at a wavelength of 1.064 cm1. The analysis of UV-Vis DRS indicates an energy gap of 3.06 eV for N-TiO. XRD analysis revealed anatase crystal structure formation and nickel's presence in the Ni@N-TiO2/Ti electrode detected at 2θ 52.8°. The usage characteristics of linear sweep voltammetry indicate that the TiO2/Ti electrode is active under UV light, while the Ni@N-TiO2/Ti electrode is active under visible light. An electrode activity test using the multi-pulse amperometry method showed that the photoelectrocatalysis performance of Ni@N-TiO2/Ti under visible light radiation reached an ideal degradation rate of 36%.

Abstract

The automotive sector has witnessed rapid technological advancements, particularly in developing electric vehicles (EVs), which rely heavily on batteries for energy supply. While lithium-ion batteries are the predominant choice, they face significant challenges, including low energy density and usage limitations. As a result, researchers are exploring alternative battery technologies such as lithium-air, lithium-sulfur, and all-solid-state batteries to potentially replace conventional lithium-ion batteries in electric vehicles. This review aims to compare the performance of these alternative battery types, focusing specifically on lithium-sulfur (Li-S) batteries, which have demonstrated an energy density of 2,500 Wh/kg. This surpasses the energy densities of lithium-air batteries (250-1200 Wh/kg), all-solid-state batteries (500 Wh/kg), and lithium-ion batteries (890 Wh/kg), highlighting their significance in energy storage capacity. Given their impressive energy density and increasing attention, Li-S batteries are rapidly advancing toward mass commercialization than their lithium-ion and all-solid-state counterparts. However, several challenges remain to be addressed, particularly in enhancing battery development to ensure timely integration into the market.

Abstract

Rice production in Indonesia fluctuates annually, often due to limited nutrient availability for optimal plant growth. A promising approach to enhance rice productivity and sustainability is the combination of biological and inorganic fertilizers. This review examines the effects of combined fertilization on lowland rice growth and yield, evaluating different fertilization strategies. Treatments included no fertilization, standard inorganic fertilization, and varied combinations of biological and inorganic fertilizers. Findings reveal that specific combinations improved rice growth parameters such as plant height, tiller number, and leaf color intensity, achieving similar or superior results compared to inorganic fertilizers alone. Moreover, this integrated approach demonstrated enhanced productive tiller counts and grain yield, indicating higher agronomic efficiency. These insights underscore the potential benefits of using combined fertilization strategies to optimize rice productivity while promoting sustainable agricultural practices.
