“…Absorbing light in an extended range of wavelengths by innovative natural dyes followed by increasing surface areas of the photoanode with a TiO 2 nanostructure-based layer on the glass substrate improves DSSC technology [74]. Khammee et al [89] have reported a natural pigment photosensitizer extracted from Dimocarpus longan leaves. According to the report, the methanol extract pigment was composed of chlorophyll-a, chlorophyll-b, and carotene components [89].…”

Production of green energy by using environment friendly and cost-effective components is attracting the attention of the research world and is found to be a promising approach to replace nonrenewable energy sources. Among the green energy sources, dye-sensitized solar cells (DSSCs) are found to be the most alternative way to reduce the energy demand crises in current situation. The efficiency of DSSCs is dependent on numerous factors such as the solvent used for dye extraction, anode and cathode electrodes, and the thickness of the film, electrolyte, dye, and nature of FTO/ITO glasses. The efficiency of synthetic dye-based DSSCs is enhanced as compared to their counterparts. However, it has been found that many of the synthetic sensitizers used in DSSCs are toxic, and some of them are found to cause carcinogenicity in nature by forming a complex agent. Instead, using various parts of green plants such as leaves, roots, steam, peel waste, flowers, various spices, and mixtures of them would be a highly environmentally friendly and good efficient. The present review focuses on and summarizes the efficiency affecting factors, the various categories of natural sensitizers, and solvent effects. Furthermore, the review work assesses the experimentally and computationally obtained values and their progress in development.

“…Biofuels include bioethanol, biogas, biodiesel, biohydrogen, biobutanol, etc (Ramaraj & Dussadee, 2015;Saetang & Tipnee, 2021). Biomass can be made from it via both chemical and biological processes (Khammee et al, 2022). With the massive promotion of industrial-scale production in the European Union and the United States, biofuel has received a lot of attention.…”

Anaerobic digestion is recognized as an attractive option for the effective management and treatment of lignocellulosic biomass as well as waste recovery of resources for bioethanol production. Long enough testing has been done on bioethanol production using lignocellulosic biomass. This helps to reduce stress and global energy problems. Global wide has a variety of environmental impacts due to its use of fossil fuels. Bioethanol might be produced in Asian locations from many types of biomasses, including agricultural waste, forest waste, and wood biomass. This would be an environmentally friendly process. Unfortunately, there is very little research into the production of ethanol from rice field weeds. This makes it difficult to develop bioethanol production. This review is aimed at developing bioethanol production and the trend towards organic products that began nowadays. Unwanted weed growth is a major problem in rice cultivation. This review demonstrated the waste-to-energy aspect of the bioethanol production process using two weeds, gooseweed (Sphenoclea Zeylanica), and small-flowered nutsedge (Cyperus difformis).

“…The main challenge of producing bioethanol from lignocellulosic materials will be the feedstock pretreatment. This step needs extensive processing to release the polymeric sugars in cellulose and hemicellulose which contributed about 20-53% of plant materials [13,19,26]. Cellulose is a beta-linked glucose polymer; meanwhile hemicellulose is a highly branched chain of xylose and arabinose that also consists of glucose, mannose, and galactose.…”

Pretreatment is a vital step in the enzymatic hydrolysis of biomass and the successive production of bioethanol. The present study is focused on thermal pretreatment (boiling & autoclave) methods of low grade and damaged longan fruits using three different types of the enzymatic sources from commercial cellulase, an enzyme from algae and mixed enzymes (i.e., commercial cellulase with algal enzyme). Total sugar production after the hydrolysis process from commercial cellulase, the enzyme from algae and mixed enzymes were 326.41 ± 08.97 g/L, 348.68 ± 01.95 g/L and 368.42 ± 01.16 g/L, respectively. Reducing sugar after the hydrolysis process generated from commercial cellulase, the enzyme from algae and mixed enzymes was 182.54 ± 03.05 g/L, 183.33 ± 04.70 g/L and 297.78 ± 02.94 g/L, respectively. Fermentation of these hydrolysate using Saccharomyces cerevisiae TISTR 5020 produced the highest ethanol production from using commercial cellulase, the enzyme from algae and mixed enzymes was 16.74 ± 0.62 g/L, 5.38 ± 0.54 g/L and 14.32 ± 1.89 g/L, respectively. Consequently, this study suggested that suitable pretreatment and hydrolysis processes are performing a significant role in bioethanol production from low grade and damaged longan fruits.
