  abstract = {<p>Black carbon (BC){\textendash}a strong indicator of diesel particulate matter and other sources of incomplete<br>carbonaceous fuel combustion{\textendash}is an important air pollutant that affects public health,<br>yet low-cost sensors capable of long-term, autonomous BC monitoring remain underdeveloped.<br>We report on the development and evaluation of a novel BC prototype sensor that<br>integrates soot collection on a quartz filter, in-situ optical transmission measurement, and<br>thermal filter regeneration. To enable regeneration at lower temperatures, we evaluated the<br>catalytic effects of various alkali metal salts pre-applied to the filter. Among these, cesium<br>carbonate (Cs2CO3) exhibited the strongest catalytic activity, lowering the temperature<br>required for complete BC removal by up to 190 �C and reducing energy consumption by<br>more than 75\% compared to that required for untreated filters. The catalytic effect persisted<br>through 10 BC collection{\textendash}regeneration cycles. These findings demonstrate the potential of<br>catalytically aided thermal regeneration in BC sensors and suggest a pathway toward<br>energy-efficient and reduced maintenance air quality monitoring suitable for distributed BC<br>monitoring networks.</p>},
