“…The measured H 2 concentration resulting from the EG solution was between 0.1 and 0.8%, which is lower than the H 2 concentration from ET at the same temperature and lower than the H 2 concentration from ET on the basis of moles of H 2 produced per mole of cosolvent atomized, 0.81 moles H 2 per mole EG versus 2.2 moles H 2 per mole ET. The measured H 2 concentration from the EG solution is also lower than the explosive limits of hydrogen in the air, 39 indicating EG is the better cosolvent from an explosion-risk perspective. The decomposition mechanism of EG is not yet fully understood.…”

Nano-and micron-sized metal particles have important applications in catalysis and in the medical and electronic industries. For applications requiring high conductivity, such as thick film conductive pastes or isotropic conductive adhesives, AgCu particles combine high conductivity with advantages of lower costs. Here, we report the generation of AgCu particles by spray pyrolysis, a process that has the advantages of simple experimental setup, large-scale production ability, and controllable particle size. Solutions of copper nitrate and silver nitrate dissolved in deionized water with either 40 vol% ethanol (ET) or 40 vol% ethylene glycol (EG) were used as the precursor. Phase separation was observed during the generation of AgCu particles, and the particles were mainly Ag-rich and Cu-rich solid solutions. The short reactor residence time experiments indicated that both the cosolvent properties and operating conditions affect the particle formation process and change the structure of particles.

“…In order to present the results in a more appropriate way, the order of the sensors in the next figures is re-arranged to follow the "hydrogen route": as hydrogen is released from the release chamber, it first comes to sensor 16, then subsequently to sensors 14,13,1,4,6,7,8,9,10,12 (not all sensors are included in this study). Along the hydrogen route, the concentrations are generally expected to drop during the release phase and that can indeed be observed at the inset of Fig.…”
