“…2020, 20, 1338 -1393 (AC2/TiO 2 ). [230] They deployed orange peels for the synthesis of activated carbon and illustrated their appliance for photodegradation of NO x ; AC1/TiO 2 showed higher catalytic performance than AC2/TiO 2 because in the DVD method the NPs entered the porous structure of activated carbon, in the vapor state. Other examples of carbonaceous and cellulosic materials derived from fruits and their application in environmental remediation are summarized in Table 5.…”

One of the most abundant wastes from all around the world is nutrient resources. Among them, fruits, their extracts, and residues comprise a major portion, which contain many valuable components that get lost during disposal or become burden on the shrinking landfills. These concerns are addressed by seeking sustainable processing methods that would have a minimal environmental impact. The crops contain renewable chemicals which are useful for catalysis, wastewater treatment, or preparation of nanomaterials; there has been an upsurge for the industrial applications of (nano)materials as their environmental and catalytic appliances is a fascinating subject to design cheaper and safer catalytic systems. Due to the excellent chemical properties of the fruit extracts, they have garnered attention as cost-effective catalysts and support materials. This review focuses on the preparation of (nano)materials and their catalytic and environmental applications and highlights the potential appliances and industrial benefits derived from these low-cost renewable and sustainable greener sources thus essentially converting waste into wealth.

“…Degradation. Typically, the photocatalytic degradation process involves three steps: (1) adsorption of organic pollutant on the TiO 2 surface, (2) surface photodegradation of organic pollutant, and (3) final product desorption from the TiO 2 surface [9,45]. In the TiO 2 /MSB photocatalytic oxidation process, the reaction was activated by the absorption of photons with sufficient energy corresponding to the bandgap energy of the photocatalyst, TiO 2 .…”

“…In addition, nanosized TiO 2 is in the form of slurry (suspension) during treatment, which makes recovery and recycling particularly difficult. Hence, to increase the photocatalytic activity of TiO 2 , several methods have been proposed, such as doping with nonmetals and transition metals [6,7], noble metal or metal ion incorporation [5,8], fabrication of TiO 2 mixture with other materials [9], surface sensitisation [10], and the inclusion of inert support [11].…”

The objective of this study was to assess the efficiency of a novel TiO2/modified sago bark (TiO2/MSB) mixture for the degradation of sago wastewater effluent by employing response surface methodology (RSM) using chemical oxygen demand (COD) removal as the target parameter. The highest COD removal of 64.92% was obtained using TiO2/MSB mixture sample prepared by combining 0.2 g/L TiO2and 1 w/w% MSB. Given that the highest removal was produced using this mixture sample, further optimisation of sago wastewater treatment was conducted by varying the independent variables, namely, dosage and contact time. Under this optimum condition, 0.10 g of 0.2 g/L TiO2/1% MSB had successfully reduced 52.83% COD in 120 min. Surface morphology, functional groups, and elemental analysis supported observations of the ability of TiO2/MSB mixture to remove COD. Additionally, aeration had further improved COD removal by 11%. The regression value (R2>0.99) of the model indicated a high degree of correlation between the evaluated parameters. These results proved the feasibility of TiO2photocatalysis as an appealing alternative protocol for sago wastewater treatment and solid waste from the industry can be utilised for wastewater degradation.

“…It is composed of dietary fiber, proteins, essential amino acids, polyunsaturated fatty acids, and potassium (Emaga et al, 2007). Giraldo and Morena-Pirajan (2014) mentioned that in the past five decades, industrialization has deflated and polluted the planet because of the uncontrolled usage of fossil fuels as the main energy source; consequently, the average global temperature has increased, thereby altering the ecosystem. In particular, according to Castro et al (2001), the internal combustion engine in the industry has become one of the major causes of environmental pollution with their excess gas emission, such as CO 2 , CO, hydrocarbons, SO 2 , and NO x , generating volatile organic compounds (VOC) and particulate matter.…”

Purpose-In this research, we have prepared activated carbon (AC) from the waste of banana peels (Musa acuminate L.) using potassium hydroxide (KOH) for carbon monoxide (CO) adsorption from motorcycle gas emission. Design/Methodology/Approach-The activation was conducted using a chemical activator (KOH) at various concentrations of 1, 2, and 3 N for 1, 2, and 3 h, respectively. Characteristics of banana peels AC (BPAC) produced were analyzed using the Fourier-transform infra-red spectroscopy and scanning electron microscopy. Findings-Results showed that KOH concentration and activation time strongly affected the CO adsorption and opening of the AC surface pore. There was an increase in the CO sorption when the KOH concentration was increased up to 3 N concentration. The highest CO adsorption from the emission occurred at 70.95% under KOH concentration of 3 N during the 3-h preparation. Research Limitations/Implications-BPAC has been used as an adsorbent for only CO from motorcycle gas emission but not as an adsorbent for HC, NO, NO x , or H 2 S. Practical Implications-BPAC can be used as the potential adsorbent for the removal of CO from motorcycle gas emission, and it is an environmental friendly, low cost, and easy to make adsorbent. Originality/Value-In this study, the AC is made from biomass and is used in wastewater treatment, but limited studies are found on the removal of CO from motorcycle gas emission.
