It has recently been reported that released metal ions such as nickel, zinc, copper and lead presented remarkable impact on the HTL reactions and could improve the bio-oil yield and promote product quality.…”

“…To date, however, no such comprehensive characterizations on bio-oil as well as biochar and gaseous products produced from Pteris vittata L. liquefaction have been performed. In a previous work, 20 we conducted subcritical hydrothermal conversion of Pteris vittata L. into bio-oils with a maximum yield of 16.88% and energy recovery efficiency of 45.10%. Additionally, we demonstrated that bio-oils were composed of esters, phenols, alcohols, ketones and acids based on GC-MS analysis.…”

“…[ 39 ] Thirdly, compared with the biological method, the hydrothermal method can produce hydrogen and organic liquids such as alcohol in a short time. [ 40 ] Meanwhile, hydrothermal conversion of biomass waste is easy to operate and can be run at low temperatures and pressures, in contrast to high‐temperature thermochemical treatment. [ 41 ]…”

Biomasses are very important natural products. Transferring biomass into catalysts for the advanced oxidation process (AOP) via heat treatment has attracted extensive attention. This review systematically introduces and summarizes two kinds of innovative biomass‐based catalysts according to the treating temperature. At low temperature (<300 °C), biomasses are converted into hydrothermal carbonation carbon (HTCC) with semiconductive properties for photocatalysis application. At high temperature (>300 °C), by contrast, the products lose their semiconductive nature and become a conductive carbon‐based conductor (biochar). They usually work as AOP catalysts by activating oxidant of O2, H2O2, and peroxysulfate for environmental treatment. This review summarizes and compares HTCC and biochar according to their formation process, structure, catalytic mechanism, and key points for the activity enhancement. The active units in HTCC are the sp2‐hybridized polyfuran unit while those in biochar are the persistent free radicals, nitrogen‐containing unit, or defects. HTCC converts water into OH radicals by using the photoexcited electron/hole pairs induced by solar illumination, while biochar activates oxidants via the active unit on its surface. More importantly, this review summarizes and demonstrates the key points to obtain high‐efficiency HTCC and biochar catalysts. Finally, conclusions are drawn and the future aspects for biomass‐based catalysis are given.

Hydrothermal merupakan suatu teknik pengkristalan dari temperatur tinggi pada keadaan campuran dan tekanan tinggi. Sintesis hydrothermal dapat juga didefinisikan metode yang menggunakan panas dan air. Pada praktiknya, metode ini melibatkan pemanasan reaktan dalam wadah tertutup (autoclave) menggunakan air. Dalam wadah tertutup, tekanan meningkat dan air tetap sebagai cairan. Ada beberapa metode hydrothermal yaitu reaksi hydrothermal,hidrolisis hydrothermal, metode elektrocemical hydrothermal, reactive elektrode submerged Arc, proses mechanocemical hydrothermal, proses hydrotermal microwave, metode sonochemical hydrothermal . Tujuan mereview ini untuk mengetahui kekurangan dan kelebihan dari metode hidrotermal pada pembentukan material
