“…Oleh karena itu, reaksi hidrolisis pada antar muka lebih mudah terjadi. Peningkatan kerapatan dislokasi atau energi regangan memegang peran kunci dalam meningkatkan kereaktivitasan paduan Al terhadap air [8]. Densitas dislokasi dapat dihitung dengan menggunakan persamaan (1.1) sebagai berikut [9].…”

“…Energi yang dihasilkan dari perlakuan mekanik yang disimpan pada batas butir dapat lebih meningkatkan aktivitas dan ketidakstabilan pada paduan. Xiaoyang Hu [8] mengungkapkan bahwa proses canai meningkatkan energi regangan (kerapatan dislokasi) dan meningkatkan produksi hidrogen. Peningkatan kerapatan dislokasi atau energi regangan memegang peran kunci dalam meningkatkan kereaktivitasan paduan Al dan meningkatkan laju reaksi antara paduan Al dan air untuk melepaskan gas hidrogen.…”

“…dengan semakin besarnya deformasi yang diberikan maka semakin besar pula densitas dislokasi yang terdapat pada sampel tersebut. Data ini sesuai dengan pernyataan Xiaoyang Hu[8] bahwa proses canai meningkatkan energi regangan (kerapatan dislokasi) dan meningkatkan produksi hidrogen. Produksi gas hidrogen rata-rata Berdasarkan Gambar 6 dengan semakin meningkatnya konsentrasi NaOH yang digunakan, tidak secara signifikan meningkatkan volume gas hidrogen yang diperoleh.…”

Produksi hidrogen melalui reaksi Metal Matrix Composites (MMCs) hasil canai dingin dengan NaOH atau air telah diteliti. Seperti diketahui bahwa aluminium (Al) dengan air pada umumnya memiliki masalah karena hadirnya lapisan oksida pada permukaanya sehingga perlu dihilangkan untuk meningkatkan reaksi hidrolisis aluminium untuk menghasilkan hidrogen. Hasil didapatkan bahwa reaksi langsung terjadi antara Al/Al2O3 dan NaOH. Hasil tertinggi perolehan hidrogen per satuan volume dari Al/Al2O3 adalah 0,660 mL/min. Ini menunjukan bahwa keberadaan lapisan oksida tipis sebagai lapisan pasif dapat dikurangi. Dalam penelitian ini Al/Al2O3 dipelajari setelah canai dingin dengan reduksi 40%, 50% dan 60%. Analisis SEM-EDAX menunjukkan bahwa senyawa AlMgSi, Oxygen, AlSi dan Al2O3 napak hadir. Analisis peak XRD menghasilkan bahwa kerapatan dislokasi meningkat dengan meningkatnya persen reduksi. Pengukuran kapasitas hidrogen menunjukkan bahwa keberadaan Al2O3 dan peningkatan kerapatan dislokasi untuk sampel setelah canai dingin memfasilitasi untuk produksi hidrogen melalui reaksi dengan NaOH. Hasil dapat disimpulkan bahwa canai dingin dan hadirnya Al2O3 adalah faktor utama dalam menentukan reaktivitas reaksi hidrolisis partikel Al.

“…Therefore, Al is regarded as a prospective energy carrier with potential applications in energy storage and conversion . Although the reaction between Al and H 2 O is exothermic (Δ G = −284 kJ mol –1 ) and can theoretically proceed in a facile way, dense Al 2 O 3 films form on the Al surface to prevent further reaction by passivating the active sites. − To avoid these effects, Al–H 2 O reactions are often conducted in acidic or alkaline solutions, resulting in environmental pollution and increased costs. ,, …”

Synchronously Producing H₂ and Purifying Methyl Orange-Polluted Water through the Reaction of an Al–GaInSn Alloy Plate and H₂O

et al. 2023

Hydrogen gas (H 2 ) as a fuel has the advantages of high energy density (122 kJ g −1 ) and zero carbon emissions. To meet the growing demand for H 2 in the future, green, efficient, and convenient production technologies must be developed. The Al−H 2 O reaction, which produces H 2 by reacting aluminum (Al) with water (H 2 O), is considered a rapid method for producing H 2 . However, Al−H 2 O creates a protective oxide layer on the surface of Al, preventing the production of H 2 . In this study, we developed a simple method for forming Al− GaInSn alloy by brushing GaInSn−Al 2 O 3 grease onto an Al plate to form an Al/GaInSn−Al 2 O 3 /Al sandwich structure. Al 2 O 3 in the sample supports GaInSn, prevents the leakage of GaInSn, and promotes its penetration into the Al lattice to form Al−GaInSn alloy. By forming a liquid phase within the alloy, GaInSn increases the accessibility of Al to the reaction. As a result, the Al−GaInSn alloy can rapidly react with pure H 2 O to produce H 2 at room temperature conditions, with yields as high as ∼93.2%. It was interesting to find that dye-polluted water (methyl orange) could be synchronically purified by the Al−H 2 O reaction at the same time.

“…In order to make Al react with water, different methods, based on the disruption of passive oxide lm on Al particles, have been developed, e.g. using an alkaline solution to assist the Al-water reaction, [8][9][10][11][12][13][14][15][16] alloying Al with Ga, In, Bi, Sn, Ca, Fe, etc., [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] mechanically milling Al metal with special oxide, soluble inorganic salt and carbon material, [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] and Al surface modication, [48][49][50][51][52][53][54] etc. All these approaches have made Al metal a promising hydrogen-generation material for portable fuel cell.…”
