“…The practical application of H 2 production via formic acid decomposition is highly dependent on the design of highly efficient and cost-effective catalysts. Alamgholiloo et al [18] investigated the formation and stabilisation of colloidal ultra-small palladium nanoparticles on diamine-modified Cr-MIL-101. Here, ultra-small nano-sized palladium particles were effectively stabilised within the pores of diamine groups grafted open metal site metal-organic frameworks of Cr-MIL-101; coordinated diamine groups of ethylene diamine (ED) and propyl diamine (PD) on the active site of chromium units of Cr-MIL-101.…”

The use of hydrogen as a renewable fuel has gained increasing attention in recent years due to its abundance and efficiency. The decomposition of formic acid for hydrogen production under mild conditions of 30 °C has been investigated using a 5 wt.% Pd/C catalyst and a fixed bed microreactor. Furthermore, a comprehensive heterogeneous computational fluid dynamic (CFD) model has been developed to validate the experimental data. The results showed a very good agreement between the CFD studies and experimental work. Catalyst reusability studies have shown that after 10 reactivation processes, the activity of the catalyst can be restored to offer the same level of activity as the fresh sample of the catalyst. The CFD model was able to simulate the catalyst deactivation based on the production of the poisoning species CO, and a sound validation was obtained with the experimental data. Further studies demonstrated that the conversion of formic acid enhances with increasing temperature and decreasing liquid flow rate. Moreover, the CFD model established that the reaction system was devoid of any internal and external mass transfer limitations. The model developed can be used to successfully predict the decomposition of formic acid in microreactors for potential fuel cell applications.

“…With huge open metal sites and specific surface area, the metal-organic frameworks (MOFs) materials have gained more and more attation in the field of hydrogen storage [17][18][19][20][21][22][23][24][25][26][27][28][29], adsorption of pollutants [30][31][32], separation of gas component [33,34], monitoring pollutants [35,36] and hydrogen production [37,38]. And it could also be used as a carrier for noble metal catalysts, especially for Pd 0 [39][40][41][42][43].…”

In this paper, a novel improvement in the catalytic Fenton reaction system named MHACF-NH 2 -MIL-101(Cr) was constructed based on H 2 and Pd/NH 2 -MIL-101(Cr). The improved system would result in an accelerated reduction in Fe III , and provide a continuous and fast degradation efficiency of the 10 mg L -1 4-chlorophenol which was the model contaminant by using only trace level Fe II . The activity of Pd/NH 2 -MIL-101(Cr) decreased from 100% to about 35% gradually during the six consecutive reaction cycles of 18 h. That could be attributed to the irreversible structural damage of NH 2 -MIL-101(Cr).

“…The biosensor first immobilizes the bioactive components (enzyme, antibody, tissue, cell) on the transducer. When the target analyte is recognized by the immobilized bioactive components, the biochemical reaction can be immediately converted into a quantifiable electrical signal through the transducer (Fu et al, 2015 ; Huertas et al, 2019 ; Alamgholiloo et al, 2020 ; Fouladgar et al, 2020 ; Karimi-Maleh et al, 2020 ). Since the rise of biosensor in the late 1960s, after nearly half a century of development, biosensor has become a comprehensive and interdisciplinary field, which is used in food safety testing, environmental testing, and clinical diagnosis.…”

In this work, a quartz crystal microbalance (QCM) sensor has been fabricated using immunoassay for sensitive determination of Bifidobacterium bifidum. Au nanoparticle has been used for amplifying sandwich assays. The proposed immunosensor exhibited a linear detection range between 10 3 and 10 5 CFU/mL with a limit of detection of 2.1 × 10 2 CFU/mL. The proposed immunosensor exhibited good selectivity for B. bifidum sensing with low cross reactivity for other foodborne pathogens such as Lactobacillus acidophilus, Listeria monocytogenes, and Escherichia coli. In addition, the proposed immunosensor has been successfully used for B. bifidum detection in feces samples and food samples. The frequency decreases of 12, 17, and 10 Hz were observed from the milk samples consisting of the mixtures of L. acidophilus, L. monocytogenes, and E. coli. The frequency decreases of 8, 15, and 7 Hz were observed from the feces samples consisting of the mixtures of L. acidophilus, L. monocytogenes, and E. coli.
