“…In the broad XRD array of extracted silica at θ = 22.5º, a distinctive amorphous solid is observed which confirms the formation of amorphous silica phase identification. According to [4], the typical diffraction of amorphous silica (SiO2) xerogel is a broad peak at 2θ = 22º.…”

“…However, for maximal potential as an adsorbent, an extremely porous material is required [3]. Therefore, many studies reported that transforming biochar into an organic gel via the sol-gel method has greater adsorption capacity [4]. Different methods of drying organic hydrogels can result in various classifications of gels such as xerogel, cryogel and aerogel when dried under each specified condition [5].…”

With an alarming amount of agricultural waste disposal rate, it emerges the search to utilize biomass and turn them into a beneficial product. Biochar is one the beneficial product that contains high carbonaceous material that is commonly utilized as an adsorbent. This research aims to characterize and produce xerogel from Palm Kernel Shell (PKS) biochar. The production of Biochar Xerogel was produced through the sol-gel method and further dried in an oven to produce xerogel. The synthesized xerogel was characterized using different characterization techniques which are Fourier Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett and Teller (BET), Scanned Electron Microscopy (SEM) analysis, Thermogravimetric analysis (TGA) and X-Ray Diffraction (XRD). The FTIR spectrum analysis has shown the existence of various functional groups such as hydroxyl, aldehyde, alkane and aromatic groups. The TGA analysis reveals the maximum thermal of 1000 °C for xerogel and XRD patterns reveal the amorphous nature of the extracted xerogel biochar. The BET isotherm revealed xerogel as microporous material with a pore width of 1.5 nm. Meanwhile, the SEM image also shows that the xerogel has an apparent pore and the pore size is varied which can function as a good adsorbent.
